HEI's work great.

Mono jet carbs really are the limiting factor in making power on a stock engine. A intake & 4bbl carbs makes a good difference in increased power.

A side draft carb intake will make the bigger gains, even on a stock engine, I forgot what Cliffird had said how much HP increase over a stock set-up? What is it guys, 40 more HP??

Found it, 40-60 HP increase. Oh my! \:D
