flywheel and clutch question

Hello, I am getting ready to start attaching my M-21 to my chevy 350. I was just wondering what size flywheel and clutch I should use for this setup. I Believe the block is from 75' Thanks.

the car is a 1970 nova. The 350 has 320 horsepower and will be used with an M21 and 4.10:1 rear Since the internals are forged and the compression is not too high I am considering nitrous also. What I am looking at now is a lakewood steel bellhousing and a 168 tooth billet steel flywheel with an 11 inch clutch setup. Does this sound like a good combination that will work. Does the 11 inch clutch require extra pedal effort? I plan on using the car for street/strip use . No long distance trips, but not beating it at the track every weekend either. Just a car to have fun in around town and at the track when I can find the time.

Sounds like a fun ride. It's been years since I've messed around with clutches and such, so I hope some one else with more current experience will post also.

A steel flywheel will hit the tires harder than an aluminum flywheel, might think about your rear suspension and tire combination.

For a clutch, I think a 11" CenterForce would be good for S/S work. I believe they have moderate petal pressure and better holding power as the RPM's increase. Might also hold the NOS better too.

If you want some expert advice, I'd call CenterForce, Hays and the company that makes the nitrous system you are planning to run. Tell them what you are going to do and let them suggest a combination that will work.

Make sure you post back what you end up using and the results. I'd certainly be interested in how your combination works as would a lot of others here too.

Good luck!

Overdriv mentioned the Centerforce clutch and pressure plate. I had one in my very healthy '65 GTO and loved it. Before that I had a Hayes unit and got some pretty healthy thighs, and bent stock clutch linkage. The Centerforce counterweights worked like they were supposed to. Once RPM's were up it clamped well and the pedal was more than acceptable for everyday driving; my wife even drove it without complaints. That was several years ago, there's probably newer technology out there, I've gone to automatics for now.

If you are going to spray the motor you need to include that when a clutch is purchased.

The sudden addition of torque from the motor when spray'd can over load a good clutch or torque converter with an automatic trans.

You need a better clutch or converter when NOS pops into the equation.

The multi disc clutch may be an answer for your application.
