i am currently in the middle of a v6 to a 350 swap in my 89 firebird, so far the swap is going real well,but i have one concern,i want to put a turbo 350 tranny in the car,i know about the 200r4 driveshaft, and the torque arm bracket from b&m, but do i use a long tail 350 or a short tail 350? also the car had an electric speedo, what do i do about that....do i just put the sending unit out of my old 700r4 in the turbo 350??? help please.......!!!

 

About the speedo you can use a short tailhousing from a buick, olds or pontiac th350, they have the larger speedo housing like the 700 and should allow you to use all the 700 speedo stuff. A chevy th350 uses a small 3/4 bullet for the spedometer so it won't work for an electrical speedometer.
