what are the old rod bearings and why so smoked? I like full grooved mains. extrude hone manifolds if they are a big restriction, maybe sneak 1968-70 units into the mix. why is a 750 holley better than a 750 Carter? if dialed in an engine does not Know the diff

Not sure why the rods are so smoked just yet. (Haven't measured much just yet) Experience tells me that a Holley is just about 15hp better than an equivalent Carter. Trust me I've done this comparison many many times. The Holley is just a better fuel mixer--it isn't about quantity here its about quality. J.Rob
