I'm changing out the 11 to 1 pistons in my 440 so I can run pump gas...my question is to keep the engine balanced can I just change the pistons then rebalance the engine, or do I have to replace the rods and crank to change the pistons??
If you stay with the same weight pistons, there shouldn't be a need for a re-balance, but if you do decide to re-balance it, you can use the same rods/crank.
