Re: Engine Vibration
yep stuff happens. rebuilder and balancing shop didn't get it where it is supposed to be, if it vibrates with just crank and FW attached
Weights may not be properly centered to each other, either
Or they didn't balance rods and pistons.
Some piston sets are off by as much as 10-20 grams
Also, if you used the old school stock type heavy pistons they are harder to get right
