Having the rotating assembly balanced and I have a late model and a early model flywheel. I assume either will work but I was wondering if there would be an advantage to the late model flywheel?
I understand from reading on this forum that the early counter weights where of a different weight. Since I was having it balanced I figured it would be corrected. The truck I am putting this 1965 I6 in is a 1985 T19 transmission I don't know if a early flywheel will match up with a hydraulic late bellhousing? What do you Guy and Gals think?

 

Balance should not be an issue swapping transmissions from I6 engines. They are by nature internally balanced. Swapping a V8 tranny to a I6 will cause an issue.

 

Hi gfw1985,
I still have the np 435 4 speed, but it's married to a chain drive transfer case. It was a 1980 so the throw out was not hydraulic.
I was hoping to use the t19. The transfer case is also a chain drive, but the bw1345 (I think it is.) Looks like it has a much wider chain.

Why won't the 1965 I6 work with the t19? Is it any thing I can correct and or can be fixed while it's at the machine shop?

Thank You for you help.

 

I found this but the it may help someone.
