First Generation Firebird-L Mailing List ......................................................................... I know barely enough to be dangerous. I have to ask, what would happen if the counterweights were all equal, but not balanced to the rods/pistons? I had a conversation about this regarding the OHC6 crank, I "believe" with Tom Langdon the OHC-6 advisor for Inliners International. I say "believe", as with my memory I am not 100% sure of anything anymore.
The conversation was about getting more RPM from the OHC6 without breaking the crank, and he said the key was to reduce the rotating mass. One important way to do this was reducing the weight of the crank counterweights, even below the balance of rods/pistons. The conversation was specific to the 6, and may or may not apply to a V8, and was not necessarily about smooth street engines. FYI, anyone interested in 6 bangers might be interested in Inliners International, who's motto is "Devoted to All Modified Inline Engines". http://www.inliners.org. They have local chapters where I have seen some wild rides. Fred Tullock 1968 0HC6 Convertible -----Original Message----- Has anyone used the trick of boring out the rod journal I.D. to artificially make the counterwieghts heavier as opposed to adding heavy metal to balance the crank? I took my crank back from the balance shop. They wanted to add 47g x 8 pieces of heavy on the radius of the counterwieghts. Two bad ideas. Of course I could make life really easy on myself and just fork out the cash for some new lightweight rods...
