Inliners International Forums General Discussion Hi Performance Dyno day for a 250

Panic,
When I built my 321 inch Jimmy I used a 308 Hudson rod, Pontiac pin and a custom JE piston. I saved more than 1.25 pounds per cylinder. I tried to find out how much weight to remove from the crank counterweights to compensate for the reduced weight but was unable to find anything.

Any thoughts/formulas,etc?.
