Question help with my 79 trans am

ok i just purchased a 1979 trans am and i also have a parts car which is a 1978 trans am which is just a parts car. the trans am that i have is the bandit edition. it has the 403 olds with the 350 tranny. the guy i bought the car from also gave me a couple of engines and trannys too that all need to be rebuilt. they are the 400 big block pontiac and a 389 and also a 400 tranny. i was thinking about putting in the 400 pontiac and building it from the bottom up and supercharging it. what i need from you all is a recipe for doing this i need a list of parts to get. and also about how much all of this is going to cost me. ohh by the way i live in arizona if there is anyone on here in this area that can offer some assistance in the trans am build-up. i know that someone on here can come through for me. so thanks in advance and sorry for the loooonnnnnggg post.

personally, if i had to start from scratch on a motor that i was going to supercharge, i think i would choose a SBC. i like my 400 in my Trans Am, but i just dont like paying up the ***** for parts. not to mention finding them first. i know that you already have some pontiac motors but chevys are a dime a dozen and there is a LOT more info out there on how to properly build them and supercharge them. you will need to get motor mounts for the chevy motor and also make sure that the tranny will bolt up(i belive it will though). if you are really seriouse about supercharging a pontiac motor, or if you want to keep a pontiac motor in a pontiac, be prepared to shell out a LOT of cash and do a LOT of searching for correct parts and information.

hey there, I know 2 or 3 months ago there was an article in High Performance Pontiac with a 79 that was either turbocharged or supercharged using parts off a cummings diesel mack truck (think thats spelt right???). I'm not sure if he had swapped his 400 for a 455 or not though, I think he might have. I have the article in my room somewhere if you are interested in it I could look for it and let u know what he did. I have an 81 trans am, and know that the 80 and 81 could have the turbo t/a option. Though they were on 301, you could maybe take this setup and do something with it. If it were my car id forget about boosting and just build a stout motor, but to each his own.
