After living in the automatic transmission world for so long, I need some advice on "rowing" gears, with a T5 going behind my 292. The short block is at the machinist, and he wants my pressure plate and flywheel for balancing. I have a flywheel off my 230 and I think it has 7/16 crank holes, and a 10.5 inch clutch. I'm sure my 292 crank has 1/2 crank bolt. So I will need a new pressure plate, right? I wouldn't think you could drill out the holes acurrately enough as a field repair.
Is 10.5 inch big enough, or should I go 11 inch clutch? I'm not racing, just strong street- maybe 250-280 HP.
Advice ???? Hays?? or other brands??

10.5" is plenty big enough.
Just have a good pressure plate that is higher rating than stock.


Like 2600 lbs or there abouts.

You can run an 11" if you would like, but a 10.5 should work fine.

Just my opinion.

Any good known aftermarket brand name will work fine.

Do not need a center force, Brand

A diaphram type pressure plate,not Bork & Beck should be easier to depress pedal .(w/the same lb rating),unless things have changed?????

In general, 153 tooth flywheels are 10 1/2", 168 tooth are 11".

Any parts store diaphram pressure plate should work fine in either size for street use. Technically, they are all supposed to have a zero balance anyway.

I do not work for Hays, nor do they compensate me.

If you want a 10 1/2" pressure plate that is easy to push and has decent preload (2750 Lb IIRC) the one in their 95-201 set is easier to push down than the stock clutch was.

That's a Mustang clutch, and is a sintered metallic facing, so likely harsher than you need. But I've seen Chevy stuff listed, with a normal disc and a similar pressure plate (but Chevy pattern).

Very nice set, I don't know what the PN would be for your setup though.

I just installed a new clutch on the 292 T5 in my '65 Pickup. It is a Fenco part # NU5551-8. It is an 11" assembly so it fits onto the 292 flywheel and the disc is a 26 spline so it will work with the T5 that I am using. Does your T5 have a 14 or 26 spline input shaft ? A late Chev Astro Van has a 11" clutch with a 14 spline disc. This pressure plate is a little on the strong side but I am towing a trailer with the truck so I don't mind it. Hope this helps you out.

Just a note:

Years ago I bought a remanufacured pressure plate,brought it to the Balance shop for balance & they could not balance it.

Brought another from same Co ,King Auto,could not balance that either. Way off center,finally 3rd one was able to balance.

Probably would have been better off just getting a new one or a brand name.

Thanks everyone, it makes sense now. I'll have to get a new flywheel, as my later year crank has 1/2" flywheel bolts. I'll get a 11" Hays diagphram pressure plate and street disc. My T5 is WC with 26 spline. I'll take everything to my machinist who will balance it again.

I'm starting another thread about hydraulic clutch.

Just have the holes drilled out, no need to go to the extra expense of getting another flywheel...

Thanks gearhead.
I see now there is no need for me to get a new flywheel, just drill out the crank holes (and resurface and balance of course)
And I asked this on another thread...both 10.5 and 11 inch pressure plates use the same mounting holes, right? So, I could use either size with a particular flywheel-just match the clutch spines (26) to the T5.
It's starting to be clear now; thank you all for the advice.

I would have to say no, the bolt pattern is different. If they were the same, you could put an 11" clutch on a 153 tooth flywheel, and there is no application that I'm aware of (with 2 piece rear main seal) where this is the case.

Just to be sure, you could take a tapemeasure to the parts store and compare a 10 1/2" and 11" pressure plate...

Thank you gearhead!
I must say, your the first person to shed light on this for me...I didn't realize 153 tooth=10.5" and 168=11" and weren't interchangeable! that explains a lot!

DuH, yes I will go to ORielly's and compare parts. I have my old 230/3 speed parts, will just clean them up and go compare!!

I feel like a dumb*ss now! Thank you again. Should be piece o cake.

if you're putting this into a early TRUCK - 3100, 3600 series truck you may need an early corvette clutch arm. this arm allows the foot clutch location moved more forward. the PP/clutch arm as seen in this first photo bends around the bell housing and allows for a cleaner assy. the adjustable arm made is just that... home made to adjust the clutch and stock pedal in a TRUCK

Thanks,
it's going into a 63 C-10 pickup.
I have the original 168 tooth flywheel, cast iron bell housing, and clutch arm.
I plan on using those pieces with traditional throwout bearing, driven by a hydraulic slave...probably mounted by a Novak mount.

see:

168 tooth could have holes for 10.5 or 11" clutch pak.

Well, another fly in the ointment.
The World Class T5 I bought is from a 93 Camaro, and for some reason, they changed to using the Ford bellhousing pattern that year.
I read that a early 80s AstroVan bellhousing will mate the Ford pattern to GM SB/BB/I6. Also, an early 80's jeep will work (I found one today, but passed on it)...except that you have to use the smaller 153 tooth flywheel and the clutch fork angle is different and there are no bellhousing to crossmember mounts.
All said, I am going to scrap my plans of Camaro WC T5 + S10 T5 tailshaft (about $1200 for both and mods and correct components).
I am going to spend the bucks and just get a Tremec TKO 5 speed. It will be twice the bucks, but heavier duty, brand new, and I can still use my original bellhousing and flywheel.
