Re: Lighter pistons and rebalance ,Question?
^ reason I brought it up is I have a crank and rod set that had been run in a 496 but I'll be dropping it into a Big M with 4.600" bore and flat top Diamond pistons. It's about the same difference but in the opposite direction, I need lighter pins than were used in the original engine but not by quite as much. My guru is shopping around and has found some that are promising but he'll have to be satisfied that they'll handle what I intend to throw at it before we go that way. Otherwise, since it has holes drilled in the counterweights, we may be able to add enough welding bead in the right spots to get it right.
There are a lot of folks that don't put any stock in a good balance job...same ones that don't believe in torque plate honing or square decking a block. I ain't one of 'em, I learned that parts is pretty much parts but there's no substitute for spot-on, dead-nuts machine work. Period.
Organized people are just too lazy to look for their stuff...
