450-500HP 360?

You don’t need a power adder to reach your stated goal. Why add the expense, higher maintenance and complexity to your build? I find turbo’s interesting, but I would want to start with a clean sheet of paper if I was to build one. I know guys have successfully run them, but not sure I would start with an LA/Magnum either. They really could use a fifth head bolt. You could go aftermarket block, but not a simple thing. I would probably lean Gen 3.

You are correct, the OP doesn’t NEED a power adder for his stated goals but boost makes this target so much easier to reach and keeps the drivability of a completely stock engine. It’s a win win. The complexity is a good argument as there is more fabrication involved with exhaust plumbing and such, but I would argue that for a street driven car it’s almost easier to do. And you end up with the hp you want AND the benefit of having a very docile, drivable engine when it’s out of boost.
