I am building an LT1 383 and I am going to replace my clutch. The clutch, pp and flywheel I have now is new with almost 800 miles on it. I was hoping to use my current flywheel but I don't know when you should go to a billet one. What is the limitations of a stock gm flywheel? If the stock flywheel is adequate I plan to use a clutchnet disc and pressure plate. Thanks.

 

Pushing just short of 500rwhp with my stock flywheel...

 

Thanks. What clutch and pp are you running with it?

 

Spec stage 4, but only because I had a smoking deal on it at the time. It sucks on the street- engages REALLY fast, and hard to get smooth launches on the street.

If I did it again I would just their 3+ kit. Rated to same power level but much smoother.
