Can anyone help me ID this flywheel... it is supposed to be a 157T McLeod Aluminum flywheel with a 28oz imbalance for an early SBF... Ive installed it during my 351 windsor swap and it's about to shake the car apart at anything above idle... Now ,I really suspect that it's a 50oz imbalance unit as used on the late model 5.0L Mustang engines.. but with no numbers or markings, and no help from the mfg, I'm looking for some help form my friends on the 'net.

Can anyone help me pout here? 28oz or 50oz... what's your opinion?

Well, after some more research... check this attached photo of these flywheels.... it's looks to me like maybe I've got a 28oz unit and the problem may be elsewhere...

The 28oz unit is on the left and the 50oz fw is on the right...uni

The engine is a 351 W from a 95 Lightning truck installed in my car... when we started her up last friday, it's got a really bad harmonic vibration at anything above idle..

Thus far, the mfg (McLeod) has been no help... they seem to be too busy to answer any questions, I've e-mailed them pics, but no resopnse so far...

Any opinions would be appreciated.

Actually, the guy I got it from had it in a Bronco with a manual transmission. He said he had the same problem upon start up because he had used the incorrect flywheel. He bought a 28oz/163T flywheel and said it worked perfectly... unfortunately, I had to use a smaller 157 tooth flywheel for my application, but it is supposed to be a 28oz imbalance unit, and based on the photos, I'm starting to think that's what I've got and my problem may be elsewhere... Internals on the engine look good, no problems with vibrations in the drive train before with the 5.0L... I'm going to call the Ford Tech line in the morning just to verify the requirements, and then I guess we'll start taking things back apart...

damn engine swaps, why can't they ever go smoothly?
