Rod Bolts - Who Made These?

That's about where I'm at. Since the rotating assembly is balanced, I'm assuming I'll have to send back everything - all 94 lbs worth. The delivery guy's gonna love me. haha.

Never trust a pro balanced assembly when purchased. My son does many engines and buys different stroker kits. We don't get many that are within tolerance. A ford f block pro balanced stroker kit over 140 grams out. 408 360 took heavy metal that is in the balancer now. Get the parts you purchased and have it balanced for your own piece of mind at a shop you trust that has a new digital balancer.

Here is a pro balanced molnar crank out of the box


Here is the same crank balanced after cutting weight from the crank. It can be drilled easy. But he cuts the counter weight to remove the weight from the diameter. Takes longer because you have to keep putting it in the lathe but look at the RPM difference it reaches due to being balanced better.
