Re: valve spring ?'s I think he's got about 60k on it. Stock internals. He's worried that since he put in a 3.73 rear With only an old 4 speed that his motor has been reving to much, but he's only put about 3k on the motor with these gears.

Re: valve spring ?'s if he hasnt raised the rev limiter then he has nothing to worry about, gears wont cause the springs to wear out, its lift and duration that cause springs to wear out....more so lift than duration, and if he hasnt raised his rev limiter and has the stock cam, then there is really no extra strain on the springs.

Re: valve spring ?'s well we fixed it. Turned out to be his fuel pump. THis car has a carb and the pump he had put on wasn't flowing enough. Thanks
