This is a 2 part question.
1 - I've heard a lot of people say that aftermarket pistons and rods tend to run tight on pin bores as well as big end bores. This is supposedly done to allow people to run tighter specs if they choose to... I'm planning to run manley pistons with h-beam manley rods in my g4cs build. My question is, should I anticipate needing to resize these or will they come true to spec?
2 - I talked to Ian at MAP who suggested that h-beam rods are only good to about 500 HP. I've also heard many a wise man say that OEM rods are a bad idea on a stroker and that you should step up to h-beam even for low HP builds. But OEM rods are good for 400+ HP... So is h-beam really even a step up? I'm planning on running some form of tdo5 turbo. This build is about spool, not big power. Is there a significant advantage to h-beam rods over OEM?
