Changing Pistons If I change to pistons with different weights, do I need to have the rods and crank rebalanced or just the crank? I am thinking about switch from 3.91" bore pistons to 4.00" pistons. TIA.

Re: Changing Pistons Ok... Currently I have a 383 Stroker with 3.91" pistons, 6.125" rods, and a 4.0" stroke crank. Everything is balanced at this point in time. I am thinking about transferring over the internals to a LQ4 block. Can I just swap the pistons out or do I need to rebalance things? TIA.

Re: Changing Pistons The pistons, pins and rings would need to be worked into being the same weight, then the crank would need a slight adjustment, nothing major. Not like they are going to have to add a ton of mallory to it, but it still costs a few $$
