Thanks LilSki. I took flywheel to a local machine shop who has re-surfaced many flywheels. The gentleman said that all flywheels get cracks from the constant heat/cool cycles, and that mine wasn't that bad. He charged $25 to re-grind mine and sent me on my way saying that this flywheel had never been re-surfaced and that it will be fine. So, that saved me alot of money and so I splurged for a Centerforce dual-friction clutch and PP. Next I need to replace the rear-main seal using an expensive $80 Viton that they claim will not leak like the rope. Then I will paint the motor and drop it back in. Can't wait. To the point of discussion, I have it on good authority that Pontiac 400's are internally balanced. But boy what alot of back and forth and confusion there is on this subject on the web.
