Flywheel help please
« on: September 04, 2007, 06:08:02 pm »
Does anyone know if a flywheel off a 4.3L will go on a 5.7L?  I don't know if 2 less cylinders made it to be balanced like a SB400 or not?  Thanks in advance...

I did it with on a 95 a few years back swapped out a 4.3 for a 350 and used the 4.3 flywheel no problems.
