SBC Flywheel
For my new motor I am considering switching from my present 11 inch 168 tooth flywheel to the GMPP 15 lb 153 tooth flywheel. Is changing the nose all I need to do to my starter to get it to work with the 10.5 inch flywheel and will I need a dual disc clutch to hold 450 to 500 ft lb of torque. The car is street only so I don't want excessive pedal pressure.

Yes that will work. Why not just get a aluminum 15 lb flywheel and then you can keep the big clutch and run a single disc. I have a Fidenza 15 lb wheel and Center Force dual friction clutch and it works great and handles all I can throw at it. .

Mine has been on for two years worth of abuse and it still looks new. Ask over on the C5 and C6 forums. Many of those guys have thousands of miles on theirs. The new ones with the inserts for where the clutch rides are pretty bullit proof. I would not worry about them warping. As long as they are installed correctly it will work fine.

I think they are referring to an externally balanced engine. They also list this for the 454 which is externally balanced. Mine is internal so no balance plate on mine.

FWIW, I got in trade & have f/s an old Schiefer Al man trans flywheel:
2 pc rms, 168T, Aluminum w/ Steel inserts. It's Neutral. NO counterweight. Looks OK. Fits 2 pc rms chevy sbc or BBC. $50 firm + ship.

Actually the housing on a 10.5" pressure plate is stronger than the 11" plate, that is why Zora went to a 10.5" clutch for the 67-9 L-88 Vette. Unless you making over 500ft/lbs of torque, I would use a 10.5" on a 153 tooth flywheel.
Centerforce lists the 67-9 L-88 10.5" clutch with a different part number than the std 10.5" offering, I think there is a heavier bellville spring on the L-88 offering.
