No i didn't pull the side cover. It was a friend of friend. I guess i shouldn't have trusted it that much. The only reason i'm wondering now weather it is the synchros is because of reading this thread and it saying to shorten the input shaft. I am not concerned with getting another pilot bushing i know that is right cuz i had it machined. I am just wondering about the input shaft because i never heard anybody say to shorten it or that it would be to long untill i read this thread. I mean the car runs great except for down shifting into 2nd. I am also going to be pulling the engine and tranny out to dress up the engine compartment and possibly rebuild my 455. I have been reading a lot of threads on here about 455 rebuilds and heads for the bbo. Unfortunetly i have J heads on the car and am wanting to rebuild the 455 to about 400-425 hp. Thanks for all the input so far and would apperciate any more input on wheather to shorten the input shaft or to bore the crank deeper...or wheather this needs done at all since i have not done it yet and the car runs fine except the downshift problem?
