I thought about it but I saw this trick done in a Chev 383 stroker and it sounded like a Jetta diesel. That I do not want--don't care about the supposed miniscule HP advantage even if there really is one. J.Rob
It's torque.
Maybe they had too much skirt clearance once that Chevy bore went out of round upon warm up.Lol SBC have thin cyl walls, a lot of them pin holed at .030-.040...
In a sbm set up to stock skirt clearance the pistons flipped around would free up about 8 or so lbs of torque and make no more noise 'cold' than something set up at .004.
Did it a lot back in the day...I use a better piston nowadays.
