I'm putting together a 64 389 tri power motor. I bought a used flywheel that i believe is correct but how can i tell before i send it out to be resurfaced. It has 166 teeth.



Thanks,
Brian

depends if it had a bell mounted starter or block mounted.The ring gear is in a diff location.Tom

I may be mistaken but I thought all 64's had the block mounted starter and had the large register flywheel to crankshaft hole.

nope, all 64 Pontiac blocks do not have a block mounted starter

Okay, so we now know it doses not take the block mounted starter. How can i tell if the fly wheel i have is correct?

It has 166 teeth on the ring gear if that helps.

I believe all big cars in 64 used a bellhousing mounted starter and the GTOs got the block mounted starter.The reg hole is NBD,if too small bore it out and if too lg get a spacer ring.The ring gear is the rub.Tom

Jim Hands book, how to build max performance pontiacs mentions this and it is wrong, at least partially. I had a 64 Grand Prix 421 Automatic, code 38S, block mount starter. Beautiful car, black with red interior, wish I had it today.
