Hey yall, I need some help and any input would be greatly appreciated. I have a 1980 Chevy short-box Custom 10. Its got a 4-speed manual tranny in it, and I wanna put a turbo 350 in its place. Whats all necessary for the swap. I have the Auto tranny w/ torque converter in my garage. I know I need the Flex plate,and linkage but what else do I need. Will it bolt right up, or will I need to do a bunch of work to it. I assume it had an auto in it at one time, because its got the dash bezel/lights and automatic steering column...Thank you for any help your able to swing my way.

get a flexplate, and it will bolt right up to your motor
Driveline length might have to be changed
as well as slip yoke and spline count and all that.
and I am too drunk to remember what else.:D

As long as you putting in a TH350 with an NP205 on the end of it, you won't have to change driveline lengths. Like has been said, you will need the flexplate torque converter, and shifters.

Ok....thats how I was hoping it would work out..Thank you for your help..
