Lets have some fun!

I'm trying to get more Hp out of my 340. I have decided the only way to go is a ProCharger setup lol. In reality I'm open to suggestions. One idea I had was to pull the engine and redo it from the ground up. The only problem is I have no idea what i'm doing but I would learn. The help I need is figuring out the specifics (bore size, crank size, pistons ect..) In order to even submit this plan to my wife (the money holder) I need to come out with a no-**** estimate. The estimate I got for the supercharger was 6 grand. Since the last rebuild on my engine has nothing but chicken scratch on the receipts I cant provide any information on what the internals of the engine are. I did do a Dyno and with everything tuned up, Dougs headers, single chamber mufflers, 904 Trans, 8 1/4 rear w/3.91 gears I got a disapointing 236Hp MAX and 278Tq. These numbers seem about what a stock 340 puts out? I know everyone here is experts and one of the reasons why I like this site is you usually get many opinions and combinations. I want to get as much Hp as possible out of a 340 so lets make me a list!
