Well, I'm putting a rebuilt 289 back in the car today, and naturally the technical questions arise on a Sunday.
I have 2 flywheels in the garage. Part number is C5AE-6380-E. Are there any opinions as to whether this is the 28 as opposed to 50 oz?
The reason I ask. The old motor had some end float on the crank, and it's just occurred to me that I should double check the applicability of the flywheel. We haven't taken it apart to diagnose yet. There hadn't been a noticeable vibration, but the car had started to burn
oil at high rpm's, so I hauled it out and had a replacement rebuilt.
It make sense to me that the 1965 casting number would be 28oz; however, one of the flywheels had been purchased with a bell that came off an early 1970's 351.
Any feedback is appreciated.
Thanks...Denis
