Default Lsx 454 build help.

So I have an LSX 454 block bored to a 4.125. It isnít sleeved down into the bottom end of the block, so Iím going to sacrifice my extra cubic inches for some more reliability. Iím gonna throw a 427 rotating assembly in it so that the piston doesnít 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 Iíd love to hear them! I know this might be a waste of a beast of a block, but itís one of my first builds and I donít want to just go insane with it like itís capable of, as itís going into a street car anyways. Thanks guys!

Wiseco pistons, Compstar rods, and a Compstar crank should work just fine.
