Harmonic balancer
 

I'm looking for a harmonic balancer for a 502. Part number on the one that I took off is 3963532, if that helps.

got 2 of them i pulled off merc 500 efi/502 they had 200 hours on them nice shape $100 each

I have 2 off of 2000 502 MPI motors

Not to hijack but I also need one for a 454 I would assume it is the same part as they are both big blocks. Haven't looked into it yet but if it works I would be interested

I'll post part number tomorrow.

I have two for 454's, one is Gen 4, one is Gen 6. $15 for either, plus shipping.

reading around i realized many say there is a difference between the 454 and 502 balancer even though they appear the same. OCBARRY I have a 94 gen 5 would either gen 4 or 6 454 work? sorry it is late and i figure you might know the quicker answer than searching the site

The balancers i have are part #1021c 8-ht stamped inside. They are for an externally balanced 454 or 502 rotating assembly's.

I checked with my engine builder. Gen 4, 5, and 6 454 balancers are all the same. It's the flywheel that is different. So I have 2 that will work for you.
