Ok I'm planning on building a 306. I want to be putting out around 450hp on nitrous. I don't want to go all out getting the best parts I can, but I want to build a reliable budget motor. I'm going to be using an 89 block. I plan on sticking with the factor style roller cam, but I think I'll get a nitrous custom grind for it. Now right now I want to know what rods, pistons and heads to use. I already have a steel crank. I want to run 9:1 - 9.5:1 compression. Also its carburated. What do you guys think? Whats gonna be the best way to get this power reliably without spending a whole lot and sticking with a 306?
