450 NA is a long shot and the cam needed to get you there will make street manners suffer, easily obtainable with FI tho. FWIW I was in the neighborhood of 410 RWHP NA with an LQ9, and was running low 12’s.
The truck now has over 600rwhp and I still drive it almost every day
Only point I was saying is that anything over 400 to the tire is going to feel like a monster on the street

On a budget lol 3100$ is still over and I would need to get an electric fan and injectors but still think I will go that way easiest way to get 450-500hp

Got the engine apart to where I think i am for the supercharger pistons look good lifters ect. My plan is to get new oil pump and seal new head gaskets and should I have my heads (317s) cleaned up and checked only 110k miles on them, should I mill them some to get compression up a little even if im running a supercharger thanks again guys.

You don’t have to get carried away with the 317’s.
If your going to boost it, I wouldn’t mill the heads any, if you have some concerns about the heads not being square, a light surface cleanup can be performed think .003”, almost nothing removed. But a razor blade does good as well if the heads are in good shape. As far as the oil pump goes, if the motor made good oil pressure before disassembly, I wouldn’t replace it. If you wish you can open up the ring gaps a bit, that will Help the motor survive a little longer against the high combustion heat
