Flywheel and clutch questions for my auto to manual swap
Hi,
I'm swapping a Richmond 5 speed into my stock '81 and trying to find a good replacement flywheel and clutch set. I was originally going to order a billet steel flywheel but I read you need to use a performance clutch set with them, and I can't really justify spending $400+ for a 190hp engine that's not going to be raced.
So I think my best choice is to order a GM flywheel, part number 3991469 from work, about $180, but what clutch to use? I can get a stock AC Delco clutch for around $120, will it work with that flywheel? I'd rather go with GM replacement parts since I can get them at work at a discount.
Does anyone have any experience with that flywheel? AC Delco sells a replacement flywheel for $100 less, but I'm afraid of chinese parts, especially flywheels.

By far the simplest solution for a stock engine would be a stock flywheel and clutch for an 81 corvette.
You can probably find a Sachs flywheel at Oreileys for ~$80 and clutch for ~$100.
The things you have to make sure are compatible are the 168 tooth flywheel and bell housing, and the clutch and trans spline count, 10 vs 26.

Went with a billet flywheel for peace of mind and I don't want to do this job twice.So far no driveline vibrations or clutch chatter.Also used a kevlar composite clutch disc that should last a long time.Watch those flywheel and pressure plate bolts they are special bolts,don't substitute use good quality hardware and torque to specs. The swap was well worth it for sure....Good luck...
