1994 clutch and flywheel
I am in the process of building up my LT1 motor to a 355 with cam, porting and polishing. The car has 85K miles and I thought I better change out the clutch and resurface the flywheel while the engine is out.
What the heck is a dual mass flywheel?
Can I resurface it?
Where can a get a good deal on a clutch kit that is heavier duty than stock?
Can I use a ZR1 clutch assembly?

Without going into all the previous discussions on this subject, you'll do just fine with the OEM clutch and DON'T RESURFACE the DUAL MASS FLYWHEEL! You'll destroy it. You need to check the dual mass play IAW the service manual. You shouldn't be able to rotate the clutch surface of the wheel more than about 1/2" or so. If it is loose and rotation is excessive, you need to replace it and it's expensive ($950). Some guys go with an aluminum single mass wheel, but you have to change your clutch design. And then there is flywheel match balancing to keep your engine balanced. Check back in the archieves and read up on it.

Thanks for the reply. Nothing seems easy on this car.
The individual building my motor feels he will get me at least 390hp at the rear wheels.
You expert opion, how many horses is the OEM clutch good for?

I had a DM that was machined twice with no adverse effects, but it's a gamble. Click this:

The geometry issue is of concern, but maybe not that big if only enought to get the FW flat is machined off.
Keeping the cutting fluid out of the inside of the DM could be done possibly by sealing it off some how.
Always observe engine and flywheeel balance relationship.
Different performance level clutch discs are available for the DM. These would be flat discs with no springs in the hub.
Look into McLeod. Also available is Centerforce, Ram, SPEC, etc etc
(advice: avoid spec)
It depends on what kind of usage your car will see.
Daily driver? Drag racing? Road racing? Auto-X?
