stroke, rod, and bore?
Most aftermarket rods are 6.125 inches with a .927 pin. What you ideally are looking for is a 4.03 bore piston for a 6.125 rod, with a .927 pin, and a 3.622 stroke. That will give you roughly 370 cubic inches.
I like Wiseco pistons and hellfire file to fit rings, have used them in quite a few builds, and have two sets of them myself that will be going in my engines I'm working on. I believe Wiseco are currently changing their house rings over to a different piece from what I've heard. For rods Eagles are a great budget option. Speed Inc has pushed 8740 rod bolted Eagle rods to over 1000rwhp. I have one set of Lunati Pro Mods with 8740 bolts and one set of K1s with ARP2000 rod bolts. I'd say buy a decent brand for the best price.
