Ok, new clutch kit warnings read:

Use only a high performance flywheel with your clutch assembly. A stock OEM cast iron flywheel, if installed, can endanger your life.

what the hell?

Hell yeah it's serious. If your engine is highly modified it'll create too much stress on the flywheel and it's fasteners coupled with the added stress of the extra clamping force of the clutch. In other words, it'll shear the bolts off and shoot them into the interior making you look like swiss cheese. That'll be a pleasant feeling, however, compared to the flywheel that will saw your legs off at the knee.

Ok, I don't think my mostly stock LG4 would be considered 'highly modified' or any bit of a powerhouse, so I assume I can ignore this warning.

Probably not. I dont think a lg4 is going to twist a flywheel off. I have seen some brake off before and its not a pleasent sight but they were running highly moded 350's with nos.

I think the warning has to do with older muscle cars. Flywheels use to be made out of "gray iron" which was pretty pitiful stuff. If it was spun to fast it simply exploded. Have your flywheel resurfaced and get a new set of arp bolts for it and you'll probably never have a problem.

caution when surfacing the flywheel. I was told once that that'll mess up your hydraulic clutch alignment and geometry and whatever. they sell spacers (I assume they go between the flywheel and the crankshaft) to counteract this change, check into it

P.S. I had mine surfaced on my '83 (it's converted to hydraulic) and didn't have any problems...yet

Just for clarification: When the flywheel comes off, the starter must too, right?
