Transmission Conversion
 

Hello, I need some advise. 1967 Chevy C10, 250 6 Cylinder with 3 speed manual transmission. Going to put in a 383 with a 700r4 automatic transmission. What do I need for a cross member for the transmission? I don't think the current cross member for the 3 speed manual transmission will work, but could be wrong. I want to get this done while I am painting the frame. Thanks.

you can use a turbo 350 cross member but the manual one wont work. i had a 350/350 in my 70 c10 and installed a 700r4 and the stock cross member worked fine, it just needed to be moved and i had to drill some new mounting holes in the frame.

not sure if you can use the 6 cyl motor mounts on the v8 install. good luck on your project!

The current rear engine mount cross member needs to be removed totally.
The V8 will require new engine mount towers and of course, new mounts.
You will need a rear trans cross member, either from a 350/350 truck or aftermarket...

As you realize, its a lot easier to do all this while the cab is off the chassis.
