So my son & I are finally going to build the 71 I've had since I was his age... We talked through work plans last night and decided we'd like to use the 305 and T-5 I already have from an 86 Trans Am donor. It's "free," and the parts lived together for 30 years already. My previous plan (swapping my 92 to a manual and using the Th700 in hte 71 went out the window because we're selling the 92). We're aiming for cheap and reliable, not fast so the weakness of the t-5 should not be a problem on a refresh of the 86 motor. Headers and a better carb will be the only changes. I searched here for details, but hits were mostly for TKO and T56. I have all the 86 parts (still have the car until someone hauls it away). I know I'll need: -modify the 2nd gen crossmember (how much?) -get the electronic speedo setup changed to run the mechanical one in the 71 (how?) -2nd gen trans hump (or just cut a hole in the floor for now) Not sure: -3rd gen pedals work? -I know the hydraulic clutch linkage will, but not sure how to align (Maybe I should cut that floor section from the 86? There are two braces on the inside, but IDK if they will ine up with anything on the 71.) Still just starting on sanding and rust repair for the body, then brakes and suspension installs, so it will be a while for drivetrain. Optimistically later in the summer, or winter, or next year--depends how hard we push and what else we find to fix along the way. Thanks All. I'll have to get a build thread up as soon as we have something to show!
