Mad, that should bolt up to a Cleveland or M motor. You’ll need a Tim Meyer flywheel spacer, you’ll need to have the flywheel redrilled to use a 460 clutch and pressure plate, that trans will bolt up to a np205 tcase with a slight mod to the back of the trans housing. Not sure about what you need to adapt it to a Dana 20. You will also need to use a starter with a longer snout due to spacing the flywheel back because the input shaft on the ZF is short. I used a starter do a 351w with a c6. I’m sure I forgot some stuff. It’s been a few years since I did mine. PM if you have more questions
