If doing an LS you might want to think about going turbo instead of supercharger. You can build way more power if you want to and custom place the turbo for your needs. No belts to keep an eye on, etc.
Or just buy the LS motor I have...its a turbocharged LQ4 block (the one all the turbo builders use), All Pro stage 3 heads built for boost by a professional with turbo and custom dyno tuned computer (800 to the rear wheels, and that was tuned mildly). She was built to handle 1200 hp. Drop her in. lol
I also have my custom built 1200 hp turbocharged 455 for sale in the classifieds here, and THAT is show worthy. Just sayin...lol

Good god that thing is a work of art! im all about making a big power car, thats what puts a smile on my face and love in my heart lol. unfortunately my father is more into a show more than go type of build here. he shot down the idea of slapping a turbo on it so its basically either bore out the 350 and put an old style blower through the hood or just drop an LS in it. we will be doing a full tubular front with disc brakes and all that so originality isnt the biggest concern. it will have full custom paint custom wheels all that fun stuff as well.
one other thing i was trying to understand is i read somewhere that all the factory pontiac firebird/TA blocks start as the same cast and are then just bored to whatever cubes designated for the model. seems there is some truth to this but not as straightforward as it seems? we dont have any desire to run the stock 350 we would want the 455 but would rather pay for the LS than the 455 if we couldnt convert the 350-455...i hope this is making sense
