upgrading?

thinking of going with the fastburn 385 and reusing my tpi setup until i can afford a better intake next year. what type of tunning would be involved with this?

anyone have the fastburn 385? i'm hoping to have roughly 450 with a good intake with this motor or whatever one i choose. any suggestions that would be better than this. i don't want to buy a bunch of parts to build one and it needs to be 4 bolt and forged with a compression that can handle a supercharger.

While Fastburn heads do have bolt patterns for Vortec and non-Vortec heads, they only have the Vortec head port design and layout. So they won't work with a stock L98/LB9 base manifold......
