I think my tranny guy is really close to fixing the problem, he left a message on my cell that he'd taken it apart about three times checking tolerances and such shouyld get it back this week. I turn this sbc about 7000 give or take 200 rpm , rev limit at 7400. In case this 400 doesn't work I'm pricing glides ATI or COAN looking good for price and reputation.Thanks for all the replies guys.
