I'm mating up a Detroit diesel to a M5R2 transmission out of a 89 F150. I have an adaptor to adapt the Detroit flywheel to a SBF flywheel. The engine is balanced already so it is my understanding that I need a zero balance FW from a 6 cyl ford. Is this correct? What year of truck should I look for when buying one?

I have a 10" clutch and pressure plate from a 302/T5 combo I would like to use with this flywheel also . will it work?
thx, Lee

 

Okay, Let me rephrase this. Is a 1989 4.9L from a F150 flywheel zero balanced and will it mate up to a 5L of the same year?
