Here's my problem. I have an old style 350 that has the large bolt pattern on the crankshaft. I have a toploader 5 speed tranny that i want to put behind it. It is out of a '89 modle. The '89 modle crank had the small bolt pattern. Can i use the old style flywheel and the pressure plate on the new style?

You may be able to use the old crank but you will probably have to use the newer clutch disk and pressure plate with it,the pilot bearing should be the same,doin stuff like this is where you get into problems,i'd order the older and the newer stuff from the local parts store and compare them side to side and see if there are any major differences.

I think the new model motors are externally balanced off the flywheel and the old models are internally balanced you better do some homework on this one .....Towman

ok lets see if i got this right?
youve got an old style engine
youve got a new style tranny
use the old flywheel(that is matched to your engine)and old style pressure plate
.use a new style clutch disc and you should have no problems
word to the wise tho check your pivot points
good luck

The reason to use the newer disk is i think it's fine splined(30 splines).
