Well im slowly making the swap to a 350 as I just bought a car and dont need the fuel mileage as much. I want to run a mildly built 350 right around 320-350hp. I'm thinking about running a zz4 cam and lifter set with a good set of heads (not sure what kind yet) the bore will just be a standard 350. Can I use a 350 290 4 bolt main block from the late 70's early 80's or a 2 bolt main from an 88-98 chevy? I don't want to convert to carb I am planning on running a tbi setup. I am also planning on having it tuned. Any help is appreciated. Also if you have other ideas for 320-350hp feel free to give me some input and specs are always nice.

Google Motorvation tbi,they offer a kit that changes the 2 barrel over to a 750 cfm tbi unit on a stock 350 you'll get 330 hp .Lot easier and cheaper that changing heads/cam.Check them out.They also can set up a kit to handle up to 440hp
