Separate names with a comma.
If this is a non cross bolted style block, I would use a 4" stroke with a long rod. You can good ring setup with a 1.395 comp distance and a...
52% for engines turning 7000+ rpm's is what I was told by the tech at Sunnen when I purchased my balancer.
15 grams would be less than .5% on most blown engines. That will not cause any trouble. The crank is balanced from the center out. If the crank...
2.5% of the total bobweight? Then I would rebalance.
If you are going to a lighter total bob weight it would make the crank "over balanced". That may not be a bad thing if the crank was balanced at...
I get mine from Murph McKinny. They are very light weight and flexable.
I also agree Noel, but the Manley spring I run on the exhaust side of my engine WILL break the tip off with the spring setup .070 before bind....
Slide them over a piece of thin metal clamped in a vice. Cut with a cutoff wheel on a die grinder.

If I remember correctly there is a auto com port selection under the system tools section.
If the crank is gun drilled, check the plug in the rear.
Not sure why someone would remove any material from a aluminum rod, but .012 of aluminum over the top shouldn't make any major strength [are...
You are past the safe zone with a 28 spline pinion. I had a few guy's ring the small pinion off with cars that were running high sixes at about...
I dynoed a Chevy with a little more head and cam, 11.5 compression and 17#'s of boost. It made 1550 hp at 6500 rpm's. It made 1220 ft pounds of...
My mistake on the name change. I have a Sunnen that spins to 750 rpm's. I think most of the others spin at 500 are less. I add 5 grams for oil....
Frank, your balancer spins the crank and bobweights at 9000 rpm's? I wouldn't want to be nowere near that machine if a bobweight came apart! I...
It's a pretty common problem with Chevy stuff. If you have enough threads on the block side of the studs, you can shorten them up enough to clear...
