Erik, Thanks for posting the picture for me.
You'll notice that the Hudson rod isn't as "beefy" as the stock GMC. However,each JE piston/Hudson rod/pin assembly is more than 1.25 pounds lighter than the stock GMC and the net results is a stronger combination. It also takes a lot of load off the crank.
We turn the engine 6000 RPM without any problems. By the way a SB Chevy harmonic balancer fits perfectly. We use a Fluidamper balancer.
The wristpin is stock Pontiac. The small end of the Hudson rod can be honed to fit the Pontiac pin.
