Quote: the .990 pin will decrease the weight of the rotating assembly and will therefore be beneficial in the long run. getting the bushing put in isn't that costly and really should be done when you resize the rods anyway. at that time i would go ahead and polish the beams of the rods since your not replacing them to eliminate any stress risers then have the whole assembly dynamically balanced.
Jerry,
I understand the reasoning behind this, but is it really worth all of the effort. A Piston with the .990" pin weighs more than a piston with a 1.094" pin. But the pin weight is less with the .990" pin than the 1.094" pin. I know that is not an equal comparison, but is it really just to close to care about. I can see a high rpm engine benefiting, but a mild performance engine wouldn't see any difference. Would it? We are talking about 10 - 20 grams, right? I guess it would have to be based upon the level of the engine build-up.
