1970 Mach I trans swap
 

Will the flywheel from a 88 302 motor work on the 351 Cleveland. I have two 70 Mach I's, one that someone installed a 302 and the other is a factory 351 C Automatic. The 302 has the toploader and I'm wanting to swap the cleveland motor to the 4 speed car.

I'm also building the cleveland motor for street but would like to keep it fast but calm. Any secrets to that motor as I have been out of the car building for 20 years now and just now getting greasy again.
