    Default GM Swap help

    Anyone have a block with crank in it out of a car? I need a measurement from the trans mating surface to crank.

    Basically how far in is the surface the flexplate bolts to from the back of block.

    I have a adapter plate from best trans. I also have a th350 built and ready. I just think I can figure out a way to use a standard gm converter instead of a hybrid.

    What Engine? There are quite a few different ways to convert from a Toyota straight six engine to a GM Auto tranny.
