I'm putting in a new clutch on my car, and I just checked the runout on my flywheel with a dial indicator and its .007". So I'm guessign it has to be resurfaced. How many times can you resurface a stock LT1 flywheel? And if the flywheel has runout does that mean the pressure plate is bad? I was just going to sand my PP and re-use it. BTW, my car only has ~4K on it since I put in the new clutch, pp, and resurfaced flywheel. I bought a T56 conversion, so I know the flywheel has been resurfaced atleast once, can it be resurfaced 2-3 times without a problem?

*edit*
Does anyone know the min thickness of an LT1 flywheel?

One more thing. Would the runout even matter since the pressure plate would sit flat against it anyway? I mean .007 is nothing, I don't see how it could hurt anything. The reason I don't want to get it resurfaced is its in perfect shape, no grooves or anything. Would sanding it to break the glaze be good enough?

I'm sure a local shop that turns flywheels can tell you the minimum flywheel specs for your application...

How much visible wear is their on the flywheel? Is there a step that you can feel? How did you measure runout? Did you run the dial indicator around a un-worn section to check zero, then check the worn area?

Surfacing it will not be a problem, you can take more than .050" off those and still be good.

I used a dial indicator after I cleaned the surface real good. I just spon the motor by hand and watched it. The surface was smooth, I couldn't feel any groves with my finger nails. I had it resurfaced today just for the hell of it though, it only cost $25, and it will only help...
