well Im 99.9% sure i am going to take my tax return and save a little and get blown! i would like some opinions on what kind to get and what doesn't come w/them that i will need to buy to go with. I can't decide whether to go with Kenne bell, Vortec, or maybe go cheap and get a powerdyne. I already have 300hp n/a and i will be running it on a completely stock short block(cross your fingers for me). I want one that is easy to install and maintain. the goal is around 450hp. I don't want to make more than that because i'm using the stock internals. Please help me decide.
