360 crank knurling?

Interesting again Jad!
So if the shop balanced your 92 as that year they must have used magnum specs hence the vibration.
If I understand that correctly.
Even though you asked them to balance as an LA… BRUTAL !!!
Well theres hope for me since this block hasn’t been run yet and assuming the flex plate I bought is correct for LA 360. I will be doing my homework on that for sure!
