Today, dollar for dollar, is the 318 faster than the 340 ???

its easy to get to ten grand in a build or at leas the high side of five anyway why stop when you get to 7500 bucks? that isn't the time to start being cheap...I guess my point is and as was said 3 grand isn't much of a budget. However say you
scored a running 340, put a roller cam in, and say the 340 would already hit 340 HP. The roller cam hopefully would add another ant least 30 HP or more.
