Clutch Recommendations
Hey guys,
I have recently finished building my 383 stroker engine for my 73 vette.
Now The only thing stopping me from mounting it to the chassis is my clutchless transmission. I have the original 4-speed and I rebuilt it so it's basically a brand new tranny.
I've been told that I should buy some sort of race clutch since my 383 is gonna be producing over 425 hp. I would like to buy a kit that comes with the pressure plate and etc.
Which brands and type of clutch do you guys recommend. I don't know how much these clutch kits cost but I am looking for a "middle of the road" price range. not cheap and not too expensive.
Thanks

I used a CenterForce Dual Friction on my BB which makes close to 500hp. This clutch has been great for over 7 years. No slippage but good pedal effort as well.

And would this clutch give me any problems during installation into the original transmission ?

The new ford engine is now using a 4.5 bore spacing instead of the old laughable 3.9. Read where it can be built to 472 cu. How long will it be before the BOSS 429 version shows up.

I love my Centerforce 11" dual friction clutch with a GM Performance Parts flywheel, polished by Boucher Racing in Rowley, MA.
Close to 460 HP and not a problem.
Highly recommend a heim joint clutch linkage kit. I can't remember the manu. right now but it was a great decision to install it!

HEY GUYS
Sorry for the long pause but I've been really busy due to school and work.
This is the info I have for my transmission.
M20 Muncie 4-speed wide ratio
Spline input: (26)
Spline output
32)
Now for the output spline, I counted 31 and there seemed to be a larger than average gap in between the 31st and 1st spline I counted. Is this normal or do I gave to replace the slip yoke on my draft shaft.
Now I will be reusing the original flywheel, it has been resurfaced, the mechanic who helped me with the engine said I it would be fine to reuse it.
Tooth Ring: 168 teeth
Original Clutch Size: 11" clutch
These are the Clutch Recommendations so far
Mcleod RST
Centerforce Dual Friction
Ram Powergrip

Another vote for the CenterForce Dual Friction.
I had an 81 Jeep Scrambler with a worked over 80 Vette 350 in it. Beat that clutch beyond belief and it was still grabbing like new when I sold it!
If the clutch ever needed to be replaced in my Vette, this would be the one...

383 with mods, street only. CFII, not dual friction, working fine for +4 years. Car has not been on a dyno, but computer sims say a little over 400 HP and 420 ft/lbs torque at the engine.
Clutch choice depends on what you are going to do with the car.

I want a clutch that could handle the hp without any hassles and easy on the pedal and reliable, but does not have to be a clutch that could handle the pounding on the strip at a regular basis.
The dual friction sounds nice but I feel is a bit pricy for a car that's not gonna be involved in a lot of strips. However, It sounds like you guys think the dual friction is great for both street and strip
