just getting my 55 chevy sedan on the road this year after a 8 year restoration.running a 454 roller motor that i had builit last winter,its running 540 HP on the dyno at the flywheel, and close to that number in tourqe.had a guy thats local drag racer, thats running big blocks in his trucks build trans.all i know is that it has corvette servo and heavy duty clutches in it.running a 3500 stall built by coan,411 9inch. talked to a trans shop,that i trust who drives a classic car himself and he thinks i took out 3rd and 4th gear clutches.next week he's going to take trans apart.my question here is,am i asking too much of this trans? I didnt consider that i was beating trans too bad.just standing start hole shots,just was taking my last ride of the year, before i put it away for the year.what are your thoughts on my situation,any suggestion.thinking i'm going to a 5 speed trans if this happens again.
