Default Resurfacing LS1 flywheel?

I have my engine and tranny out right now for some repairs (engine sucked up water, bent a rod) and while everything is out I figured I would get my flywheel resurfaced since I don't have enough money for a whole new clutch assembly. It's got 85k miles and has some scoring on it, and my friend said that he thought he read somewhere that you couldn't machine the LS1 flywheel due to tight tolerances or something but he wasn't sure. I talked to the machine shop at my work and he said it didn't say anything about not being able to do it. Just want to make sure before I take it in.

Ive done it. Never had an issue. Theres a lot of people saying you cant do it... but thats just hearsay. I highly doubt .007" is really going to be noticed. I wouldnt continually do it, but one time wouldnt be an issue.

If you do decide to do it, make sure you get back on here and post up your results so these people who have never done it and believe its going to blow up your transmission will STFU.

Thumbs up

I just put a new clutch in my 01 z28 on wednesday and had mine done. He said he took off 12 thousandths and it holds fine. Only cost 20$ bucks too.

You don't want a broken-in pressure plate surface w/ a new flywheel surface. That would be the same as putting a new clutch on a used flywheel.

If the clutch worked fine before, leave it be. Some scoring is subjective; some discolourization of the flywheel is going to happen and again be normal; got pics?

If you had to replace the flywheel for some other reason, you'd want to have the PP turned or replaced so you could break it in together as-new.

Last I checked around there was no minimum thickness spec anywhere nor printed on the wheel itself. I know people who have done it with no issue.
