Inliners International Forums General Discussion Hi Performance 292, is this doable?

Lets say a man has a 65 chevy nova.

Believe they are around 3000 lbs.

Lets say it would be 99% street driven.

The 1% of the time its at the drag strip, it must hit the 12's, in the quarter.


Anyone know of a 292 combination to fit the bill, street friendly with some umph?


Id lean towards naturally aspirated but if you have a nitrous/turbo combo, lemme know how she does. Include tranny and gear ratio info.


Tryin to convert an old boy to the ways of the inline, gimme some info to spark his interest.


Thanks

well you have a pretty big order to fill. 12's are going to take 450hp in that car. i'd say for a driver a turbo is the most dependable way to do it. nitrous will also get you there and be cheaper to do. but it is way harder on parts. my engine combo is at the level you need. i have written it up before, but it ain't cheap or easy. you can see my write up here www.inliners.org/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=3;t=000816#000000 . p.s. i'll get those pic's you wanted. tom

From the two 292 Chevy IIs I have had, 12s even at sea level in an easy to drive car, will be very difficult without forced induction or nitrous.

My 66 2dr all steel sedan with full interior, stereo, pump gas 292 with solids, 4 speed and 4:10s ran low 14's at close to sea level. My all steel 63 with gutted interior, strictly race 292, glide and 4:56s ran mid-12s at the same track. The car without driver weighs 3100 lbs including a 6pt bar and subframe connectors.

To do what you want to do without some sort of adder, you will probably want a lot of gear and an overdrive trans to make it liveable on the street, a lot of fiberglass body panels, maybe lexan side and back windows etc. For 99% street car, I would shoot for 13's and have a very nice driver.

No kidding 450 hp.

I tell ya why his goal is 12's.


His first truck was an 83 s-10 blazer daily driver, had a stock 454, wish I had a big brother when I was his age , well had intake and carb, still nothing special, turbo 350 and high 2.**:1 rear end, open rear. He drove it daily, put slicks on it and go knock out a high 12 in the quarter.

After that we then put a built big block that dynoed 470/520 at the crank and it would flat lay you back in the seat, along with the posi 3.73:1, higher coan stall converter, he never ran it with that last combo, too bad, it was a blast, was still his daily driver, , my point being, the original powerplant by SOTP felt way below the 470 he was getting out of the new engine. The blazer weighed in around 3500 without a driver, which kinda suprised me when you said 450. I can imagine the BB torque is the main contributor his results, still took me by surpise.

Why the long story, this is gonna be his logic to run a v8, so I need some good news to share with him, about the inline, know what I mean? Just to be different wont cut it, hes leaning towards a efi 6.0, I dont know how many LS engines are in novas but Im guessing few, so this is more unique than a warmed over inline or SBC. Again, this is gonna be HIS logic, so bare with me here.

Now Im a fan of the inliner, never knew why, just happened that way, Ive shown him all the combinations (vehicle,engine, tranny, rear, times) I can find, videos, etc., there is a small spark of hope.

So if anyone has a combination that really hits close to what Im asking, throw it at me. Lets convert this ol' boy.

Thanks, tlowe, look forward to the pictures, any numbers on your el camino turbo'd 292?

Thanks, bruce, looks like this could get involved for sure, you know any guys with nitrous 292's and chevy II's that like the street as much as the strip? Appreciate the information!

Fellas, feel free to throw more thoughts my way, if something comes to mind.

You'll need to use a 250 pan On that 292 Because The 292s Oil Pan WILL Never EVER clear the drag Link. But a turbo is really The best way to go. it also Doesn't Take any Hp for it to MAKE HP.

Sounds about right. We were putting down 325ish @ the rear wheels with my old v8 and running 12.80's

Ya'll keep this up, its gonna talk him outta the nova all together. He'll be sticking a stock BB in another s-10 blazer. KIDDING.


I like the idea of a turbo engine, hes not too interested at the moment but keep the ideas coming, who knows what tomorrow holds.


I was looking at the inliner rides gallery and it seems a blower works really well on the inline engine, with little boost. I just know there is no way hes gonna cut the hood, much less off to the side.

Maybe a procharger would get it done.

Fellas, tell me some good stories about how you made 4-450hp with the inline engine and how its street friendly, forced induction, nitrous, or naturally aspirated.

For what is worth, there was a 66 hardtop here with a nitrous boosted 230 and I am not sure of any additional details, but it was a all steel and full interior street car. He ran mid thirteens here which would have put it very close to the 12s at sea level.

I would guess if your friend is thinking of a LS1-LS7 type motor, he is going with an aftermarket front clip. If he is planning on that, then it opens up all kinds of options with an inline space wise. With a clip, he can fit 3 Webers, a roots style blower and Vortec style superchargers become much easier.

Also, check out the Camaro at http://www.goravenswood.com/engines.htm It is in the 11's; Twisted knows the car as to whether it is anywhere near street able or not, but it may help sway your argument.

Thanks man.

Yeah, I bugged T6 about that camaro, he was tired of talking about it Im sure. Its also big cam and not anywhere near streetable, Im told, I shown it to my brother, provided all the information on it I could gather, it did get a smile out of him, especially the video. Maybe if I we could offset the need for a big old cam with some laughing gas, it might work out.

This is my youngest brothers car, right now he would like to run an aftermarket clip.

Ive dug into some research on the LS swap for him, I wanna be sure he has all the information available, one way or the other, seems he can use the stock clip, just a matter of using a GTO LS oil pan and custom headers ~ maybe. Just adds to the information, nothing is set in stone yet.

Just so many options.


If you remember anymore combinations, throw them my way.

Appreciate your time and thoughts, thanks!

300 Somewhere On this board is some Photos Of Harry Stirnemanns 1937 coupe 292 turbo Street Legal. He used to run the Hot Rod Power tour. 10.13 @130. I don't know If he still does the power tour Or not.

T6

I tried a search, couldnt find anything.

About five or six years ago, there was an article in hot rod magazine, shown a coupe running a 292 turbo, believe he was using efi and everything from a grand national, kind of a light tan, beige colored car, would that be it? I remember the author stated, as he was being driven to the photoshoot or something like that, he was unimpressed, as it seemed like a stock jallopy or something to that effect, etc., then when the driver got into it and built up some boost, he was impressed.

Maybe I will find it on the net.

Thanks for pointing that out T6. If anymore combinations come to mind, throw them my way.

Guys,

RevOD posted some photos of Harr's car last fall.

Posts with photos of Harry\'s 130 mph Chevy

Thanks Hoyt!!! That is the car I was thinking of, its nice! However, the article i read, I think he was using efi, not the current triple carbs, wonder what it runs now..jeez.


NOVA LOVERS...

gimme the bad and the ugly of using one of CPP's mini subframe kits...or tell me its a good deal. As that kit along with disk conversion for $1g, sure looks better than $3g for the full aftermarket subframe kit. Any thoughts on that issue, appreciated.

Harrys car used to run a 1100cfm Dominator and switched over to Triple Duces 2 years ago. I havent seen the car in a while so im unsure if they are using EFI now, but I though I heard talk of swapping on a Jeep 4.0L head?

300 look at this for set-up for the nova.
http://www.classicperform.com/ for the front end.
I never did the mini I went for full tubs. and My car still sits on the Factory springs all around.
Back seat & 8 point roll bar.

Oh, I wasnt suggesting they were running efi now, many years ago there was a write up in hot rod magazine, I thought it mentioned grand national efi but I may have been wrong, it may have just been the turbo, at that time.


Whats with inliners running big old carbs?


A 4.0 head on a 292?


Thanks T6, Ill check that link out.

Anyone familiar with this kit? Pros ~ Cons?

http://checkeredracing.com/62-67Nova.html

Thanks

I for get who And I'm looking Some one does make the bolt on front clip WHICH IS Not the mustang two. AND better.as soon as I find my papers I'll let you know.

Thanks T6

Ok I got it Chris Alston's Chassis works
www.cachassisworks.com They have a Bolt on front clip I have been drooling over for a few years now.I'd love to stick it un mine. It would drop Like 300 plus lbs Off the front end. And IS NOT like i said mustang two at all. I know I called them on it. and ask if it was the mustang stuff.
AND they told me Heck No. The Mustang2 had more of a bump steer problem then the ChevyIIs did/do.
They also Off set it I think??? like 1 in back for more clearnce for 15in tires and it is a lower
Then stock but not a big amount. But anyway check it out.

I think a turbo is the way to go but I have a machine shop at my finger tips. The next option would be a centrifgul blower/super charger w/blow though carb. Guy's have been doing this setup v8s for years and have good results. The bottom would be good rods and SRP pistons. The cam would be a mechincal with good valve train componets. The head would be a Kirby lump port (dont skimp here!) The igntion would be MSD with crank trigger w/boost retard. The blower and carb are you'r choice. The trans would be a turbo 350 w/3500 convertor with 3.70 gears and 26x10 rear tires. Plus, a 50-75 hp shot of nitrous. You have the volume of air with the blower now you have the quality of air with the nitrous.

This is a basic setup I think would be pretty easy to build and would be a nasty hot rod on the street.

Steven

I hate to bump an old thread, but the reason your friends S10 would run that fast was cubic inches. The fat torque curve from a big block (at least 450-500 ft-lbs) plus highway gears makes for a pretty impressive ET. I ran a stock '70 vintage 460 from a Lincoln in a Fairmont, and that thing would run low 12s all day long! And I was running 2.75 gears too boot!
I definately agree that a power adder would be a necessity to make up for lack of cubes (at least to be tame enough for the street!). Just a little extra input.

Dear Phil;

Exactly. :rolleyes:

It's "nuts" to think a 3,000# vehicle will run in the "12s" with less than 300 CID and be driven 99% on the street.

There might be some exotic import that could, but not with a 60s truck engine for power etc. To quote one of my Engineer friends; "America's 'Hot Rods' are just a lot of noise & brute force".

I like noise & 'bute force' but there are limits, even to that.

Thanks for bringing this up.

I don't claim to know anything, but a 250 chevy should make 350hp easy with a turbo. and 350hp in 3000 lb car should run 12's 100 mph+.
Also a turbo makes lots of torque and only needs to turn 5000 rpm to make hp not 7000 therefore it is easy on parts , this is what makes it a great street setup. the compressor flow is what determines the hp limit not so much the engine size.

I think a 250 w/ stock crank, stock rods w/floating pins and ARP bolts, (I have made 500+ hp with 292 stock rods), TRW forged pistons w/ good rings (not moly,if you detonate it),
220* at .050 114* L/C cam, bump port head w/ stainless valves, stock HEI w/MSD digital 7 & coil & good wires, INNOVATIVE exhaust manifold and wastgate ,A duel 2 barrel manifold with C&S aerosol carbs , air to air intercooler , 60-1 turbo w/Q trim turbine w/.81 a/r . 10# boost= 350hp, turbo will make 550+ at 20# boost (race gas),

any automatic trans with 3000-3500 stall,
3.90 gear w/ 28" tire


just my thoughts.

My Camaro ran mid to high 12's w/a Paxton, 250 CI engine running 9 lbs of boost.
Approx 3300 lbs w/driver.

Three 48 MM DCOE Webbers. 410 gears, 3000 stall.

MBHD

Agreed.

However; these engines/cars are far beyond what the 'adverage' person can accomplish/create and a BIG exception to the norm.

now that someone makes an exhaust manifold it's easy to do you don't even need an intercooler just run a hose to a single carb and hold on !

Sure; In your dreams!!

If it were that easy, there wouldn't be anyone running 13 sec. +/-

This is a professional website and not to be used for 'teenage' banter!

Happy trails.

Sorry if what I posted was considered "teenage banter". I have been reading posts for many years, but did not feel comfortable posting on the web.I have been a member for many years and running the "late style" inlines since the 60's. I started with turbos in the 80's with my 37 chevy coupe that ran a very simple draw through setup. At the time it ran high 10's at 3200#. Now that the hardest part is available, the exh. manifold, I feel it's easy for anyone to turbo their car. I will be glad to try and answer any questions. I'm listed in the Inliners roster.

Harry Stirnemann II # 772

Turbo-6,
I am glad to hear from you on the board here!!
What's next on your 37?
I even got an old popular hot rodding mag on Ebay just because your 37 was one of the cars in the magazine.
I typed in your name & that magazine came up on the search.

MBHD

Hello Harry

Glad to see you on the Board after so many years.
How is the New turbo set-up going so far?I'm sure
many here will Welcome your turbo experience.
As well as benefit from it.

Hi guys, thanks for the interest in my 37 . It's apart now with a bad thrust. Trying to run more boost pressure and the siamese port went nuts as far as the fuel mixture was concerned. divided the port and fixed the fuel problem but created another with very poor flow numbers, wished I had purchased a Kirby 12 port when I had a chance. Racing on a budget SUCKS !
Anyway you guys are way ahead of me with EFI etc.
and can't wait until you get your setups going.
I also keep in touch with Leo and he also had some weird problems last yr. Maybe we can all get running at the same time, wouldn't that be cool. Maybe the 08' convention, I need to get to one of their meetings, but something always happens I have too many irons it the fire!! and don't have much time for my 37.

I do not believe a 12 second streetable six cylinder Chevy II is not unreasonable. Nitrous on a fairly "normal" hot rodded 250 could do it and still be very streetable. Forced induction would probably be better, but the complexity and engineering required does go up. My Chevy IIs have not been real quick due to going old school with plain old carburetion.

I doubt anyone here will deny that $$/HP is higher on an inline than a V motor, but the HP to get in the 12s with enough money or personal ability is not out of reality.

i also think there are alot of readers and are reluctant to add into a forum because they may be ridiculed. sometimes we need to be more open to others views.
harry , i am glad to see you are willing to add to these forums. i have read the articles and wondered, just how did he do it? hats off to you! you are correct, with the availability of quality turbo exhaust manifolds and at decent prices. more people should get familiar with turbo power. it is easy with a turbo and carb as revod has shown everyone.
harry, what size turbo are you running now and what kind of boost pressures do you see? is your car intercooled. tom

I run a T70 with a Q trim turbine, but just changed to a S trim turbine, back pressure has anways been a big issue on my car. was running 25# boost and now with my ice water to air intercooler going to 35# boost. as I said dividing my intake port cut the flow by 25% and I feel I need the higher boost to make up the difference, will see.
Been working day and night to get a car ready for Pebble Beach this Aug. and don't know when I will get it running again.
Hope the new forum gets going and see what other combinations people are using.

Harry

Hey harry good to see you on here, we've talked a few times at the Fenton Cruise, you know my Dad, Dennis ODonnell. Once I get my Turbo 6 on the road ill have to swing by the shop one week.

BTW you guys have any plans for that Firehouse your bought?

RevOD stop by bring your dad, you know we are cousins or something.
firehouse is for sale now.

Yeah like what cousins 6 times removed lol.... What nights are you guys normally up at the shop?
