First thread, hundreds of views. BTW thx so much to all replies to everyone's questions especially GTOguy and Bear! After intense 3 yr resto on my # matching GTO I am looking at upgrades. It was born with and since rebuilt to stock 389 4 BBL and ST-300 with 3.23 LS gears. Added aftermarket Tripower and MSD and soon to be Ram Air 2.5 mans and pipes. I am looking to change cam to maybe Comp cam magnum 51-233-4. Will tranny handle this with no converter change? Also is a tranny change smart (700R4 or 200R4)? Is only street driven but want some more jump. I am in Canada so if I ever sold it I don't know if # would mean much. Any advice would be appreciated and sorry in advance for all the keystrokes (True apologetic Canadian)!!
