I have 2 LT1 motors and trans'
1. a 94 Vette with 4l60e
2 a 94 Z28 with T56

I want to switch transmissions, so I can put the Vette motor with the T56 in my '70 RS/SS. And the Z's motor in my 71 K5 Blazer. with the automatic.
Other than switching the harnesses, and PCM's, what else do I need to do. Do I need to have the flex plate balanced to match the flywheel, from the other engine, and vise versa?
I know its a pain, but I want the Vette motor in the Camaro, with the T56.
Thanks, Steve N

 

Hmmmm....
nobody?

 

No need to worry about balancing the flexplate or flywheel. Why are you wanting to switch the trannys? Has the vette motor been rebuilt or something?

 

yes, the vette motor has less miles. I also want to run the AC in the '70 Camaro, so with the vette belt setup, I can have the AC without notching the frame.

 

The LT1 engines are the same so yes you can stuff the T56 behind the Vette engine and install it in an older car or truck .
