The cloyes gears are a degreed set. which is a little more but not by much.

More updates. I got my pan and rocker cover back and painted up.



Also I began work on making a custom adapter for the Holley 500cfm 2bbl. Had to make my own to put the fuel bowl up front instead of 90deg like the offy adapter puts it.

I got my balancer today. a SBC balancer cut and groved.... very nice fit. Also using a piston stop I verified TDC and remarked the timing line on the balancer itself.

Looking good!
Not sure if you done it already but you can port & open up your exit on the exhaust manifold & run a larger pipe for better exhaust flow.
Got anymore pics of your balancer w/the grooves?

Hank any instruction on how to port that open I would love to know how. As for the 50cc pump yeah i figured it might but it was on the carb when I bought it. I have a 30cc one if need be to change it.

I can get some detailed shots of the balancer for you tomorrow. The guy did a great job.

Hank BTW do you have any pics of your setup in your camaro as fas as turbo location? Im wondering how to mount a small turbo off the stock log.

The 292 exhaust manifold will bolt right up, it uses a 2 1/2" pipe and has a three bolt flange. But it looks like you already have your stock manifold looking pretty nice on there.......

Diesel Dan is right , if you can locate a 292 manifold put one of those on instead of porting your 250 one.
Porting is done by grinding w/a porting tool, electric or air type.
Use a carbide cutter & just grind the opening bigger.
I think you might get close to 2 1/4 opening?maybe???, if not that big, anything will help, I think it is smaller than 2" as they come stock?

Maybe some guys here have some 2.5" manifolds lying around??

Yes the (large) 292 manifold is the best choice. \:\)

It only comes on the series 40 trucks though. Otherwise there the same as the 250 with the (2 bolt) smaller pipe.

There hard to find as well.

Good luck. \:\)

rev, another tip for you. truck motors(1/2 ton on up) used a different motor mount that bolted to the block. it is shaped to accept a small block chevy rubber motor mount. these are much better at holding the motor than the thick rubber ones used in cars on sixes. these were used on 250's in pickups. you will also have to use the corresponding v8 bracket for the frame. tom

so you are saying, get a truck rubber mount.
But if you do, you need a V-8 frame mount?
Or?????
Did you happen to take any pics of your 292 mounts in your 65 Elky?

No joke huh. See im going from a 8 to a 6. I got the 6cyl frame mounts but one is taller then the other. You saying that if I can find these truck motor mounts I can use my V-8 Frame Mounts?

Here is my issue right now. One frame mount is taller then the other. Anyone know which ones goes on which side? This is for a 72 Nova

the mount you have shown in one of your pics is for a car application. on a 72 nova, it still uses a 3 bolt rubber mount correct? if so keep your v8 frame mounts and find some pickup 250 engine mounts. 292's use a simulair mount, with a v8 style rubber mount. only the driverside will fit from a 292 onto a 250. the pass is different. all this keeps much better control of the motor, less flexing. these engine mounts are found in 63- atleast 72 chevy pickups. tom

it sometimes seems like i have to do all the leg work. here are some pic's of 292 mounts that accept v8 mounts. all 292's used them, only truck 250's had mounts simuliar to these also.

Thanks Tom!!!
Another question,,, with the 292/250 truck (thinner rubber) mounts, does the engine sit at the same height as the thick rubber mounts?

Yeah man that deffenitly looks like it flows a ton better. Not to mention with the horizontal exit it should make turbo hookup a bit easier. Ill have to call a few local junk yards to see if anyone has one. I can only imaging shpping would be a bit much on that.

When the 292 Series 40 truck manifold is installed on a 250 with a manual transmission, will the attached exhaust down pipe interfere with the clutch linkage attached to the engine block? Is there a resolution?

Thanks

It may I don't know, as I've only used them on the 292 engine.

I would think the Muffler Shop could "give her a bend or two".

Unless your building a "really hot" 250 engine, just use the stock one, as the only difference in at 'high' RPM. The "really hot" ones use headers to get even more etc.

Good luck. \:\)

Would you please post a picture of the grooved balancer for us to check out. I'd like to get one made too. I'd like to find a dual 4bbl Offy intake for my 250 for two single barrel throttle bodies like Jim Linders truck.

Might be good news... found out a friend of my fathers just happens to have a 15K mile 230 (i believe) from a 65 chevelle. Its the original motor was pulled and stored inside. Contacting him tomorrow about it. If it turns out to be a 250 ill swap the whole thing in.

RevOD,

I was wondering if you had the damper turned down on the center section, so the damper sits closer the the timeing cover?
Thanks

Here is is after the install before we pulled the head. Tons of room for the turbo and a small FMIC too. I also ordered a Pertronix kit for the distributor.

A few more things are on the way. A Boost gauge and cup, an LC-1 Wideband Controller that will power my already installed Autometer narrowband gauge for quick reference and a Moates "O" Meter for more accurate info and data logging.

The machine shop starts work on the head Monday so hopefully that will all be squared away within the week and I can fire this car up and drive it. Im stoked to get the turbo housing and flange back so I can start welding up the turbo exhaust.

I am going to just use the stock manifold and attempt to make a tight enough bend.

Sounds good!
I would suggest using a stainless tubing for your u-bent part. Using a plain steel will corrode in no time & get weak.
You can buy thick wall stainless u-bends on Ebay

With schedule 40 or so,, thick wall tubing , it will support the turbo much better.
They are already chamfered & ready to weld.

You can buy schedule 40 stainless tubing or plain steel from McMaster Carr.http://www.mcmaster.com/
They have different angled pieces to fab your U-bend pipe.
Or get some ideas here: http://www.sdsefi.com/tech.html

Fabricating a Turbo Header

Should not be too complicated.

Any more Q's,, let me know, goodluck!

Yeah ive though about that problem is I don't have a setup to weld aluminum. Although I have thought about using Steel Sch40 weld els and pipe for it.

Well as I dont have the setup to do stainless I did start on making the header with Sch.40 Iron Weld Els. A bit heavy but should work fine. Then eventually I can build one with stainless.

Pic is a bit big but I didnt have to to resize it.

Looks good!
The schedule 40 weld els , are supposed to work fine, + it needs to be thick (which they are) to help support the turbo if you do not make any other brackets for support.
