Long story short. 84 GP. Original v6 car. Trans blew, put in a BOP 2004r. Pulled out motor and trans and threw motor in garbage for engine swap (hence why I got the BOP because I was plannng the engine swap anyways). Currently have a 350 olds rocket installed that came with a t350 and I’m running the original (2.56?) v6 rear end. I’m changing out the rear end with a Richmond 4.10. Problem is with the t350 I won’t be able to freeway drive anymore due to the high gear ratio and no overdrive or forth gear. So.... I’m thinking of putting the 2004r back in (possibly getting it rebuilt ) when I do the rear end swap. (Driveshaft fits both transmissions) so two questions. First. What do you guys think of the idea ? And secondly, I remember having to change the trans mount when I did the motor swap. What will I need to do as far as the cross member and trans mount for switching the trans back if anything ?
