Junkyard 5.9L Magnum + Edelbrock LA heads build

Also for the record my thoughts on adding boost are mostly to counteract the lower air density at my altitude. I'm building the car primarily for road racing and 450 HP is too much for the rest of the chassis as it is now, let alone 600+ on a road course; I'm thinking if I ever get the itch to take it to the drag strip I'd be tempted to throw on a Procharger at low boost mainly just for straight-line shenanigans. I just want to have some "room to grow" and not need a full engine rebuild once I want more power which we all know always happens eventually :D
