Hey everyone, just wrapping up my build on my BBO 455. It's putting out over 600HP and 700 ftlbs of Torque. I will be dropping it in my 87 Olds 442. I currently have a Ford 9" rear with 3:91 gears. I have no transmission at the moment, I got rid of the 2004r years ago before I started the build and now I'm kicking myself because it's hard to find a core, My question is, do I go with a built stage II 2004r or go TH400. The car is not going to be used for long-distance, I could care less about MPG's, I just want to have fun on the street and maybe take it to the strip from time to time. I know the cross members for both trans will be the same I will just need to get a new driveshaft which I had planned to do anyway due to having the 9". Just looking for everyone's opinion on what would be the best way to go as well as recommendations on where to buy the best transmission. Any advice would be much appreciated.
