Trans
 

I have a 71 gmc long bed n i just got a turbo 350 trans w/ **** kit ect. My truck came w/ a 3 speed on the tree do i have to change the crossmember to an auto one or can keep this one im puting in a 350 . If anyone could tell me any probs im going to run into w/ the motor n trans just let me know. Also let me know what u guys did w/ ur drive shafts .. thanks alot

Your driveshaft should work long as your th350 is a 6 inch tailshaft, you will have to remove the manual crossmember. Which is the hardest part of the whole swap I thought. I took a sawzaw and cut bothside as close to frame as I could. You will ne an auto tranny radiator and steering column unless u use a floor shifter.

the crossmember has to go no way around it. you will need an auto crossmember. a flexplate for an auto trans. also will need a shifter. dont have to swap the radiator. you can just get an external trans cooler which will work better than the radiator anyhow

You'll also need a starter too if your truck still has the original style one on it. The original standard trans trucks used a starter with cast iron nose cone which bolts to the bellhousing with three bolts, rather than to the block like auto trucks and all later model trucks used.
