i'm ordering up some new cam, rod, and main bearings today. i decided on the summit parts but i'm trying to decide between their "standard" and "high-performance" bearings.
The rod and main bearings are all silicon aluminum (bi-metal).
The high performance rod bearings are chamfered, while the standard are not.
The high performance main bearings say:"Larger chamfer for crank-fillet clearance."
The standard cam bearings are made of steel backed babbit, while the HP ones are made of silicon-aluminum.
Any help on deciding here? They are going into a Goodwrench Chevy 350 with mostly stock stuff, except Edelbrock Performer cam and intake manifold. Thanks guys.
Edit: I also need to order a timing chain kit. I'm gonna match my cam with an Edelbrock kit, but I'm trying to decide if I need one with multiple (three) keyways, or just get the emissions one keyway one. Not sure about that too. Thanks!
