Lsx 454 build help. So I have an LSX 454 block bored to a 4.125. It isn’t sleeved down into the bottom end of the block, so I’m going to sacrifice my extra cubic inches for some more reliability. I’m gonna throw a 427 rotating assembly in it so that the piston doesn’t stroke too far out of the bottom of the cylinder like it would if I used a 454 rotating assembly. So with that info given, I need help on picking out a compatible and reliable rotating assembly, cam, heads and intake. I want to go on the cheaper route with it, with a goal of around 500hp. So if anyone has any suggestions I’d love to hear them! I know this might be a waste of a beast of a block, but it’s one of my first builds and I don’t want to just go insane with it like it’s capable of, as it’s going into a street car anyways. Thanks guys!
