I have a Chevy 400 at the machine shop right now. If the block checks out I plan on supercharging it and running an internal balance forged crankshaft. The current goal is somewhere in the 550 hp range. My question is this, what would be a good bearing choice for both the mains and the connecting rods?

.0030"-.0035" mains, .003" rods

One of the machine shops here says he sees a lot of durability with King bearings on the circle track engines he builds, says the guys tuning a lot of these are way off and detonation etc. doesn't hurt the King bearings as often as clevite and others. I bought King for my BBC but haven't put her together yet. Bob

I also have heard good things about King bearings. If my supplier had them, I would try them.
