OK, I have a 1971 360 motor which stock came out with a 2 bbl horsepower rating of 255 @ 4400 rpm, and torque at 360 @ 2400 rpm. Now, it has a performer intake, and I plan on putting on a 4 bbl but still need suggestions on which one would be best for a quick street car. I am told that it's not so much how much gas is dumped in, rather the air-flow gas mixture which makes an engine quick. How can I cheaply and safely get more horsepower, and maybe torque out of this motor, and what would be the best carb to use? I read that it is not always better to use a double pumper, but rather a good vacuum advance instead, maybe a 750 cfm, rather than a 600 double pumper. I want response, and overall performance. I want to build it right the first time. It will be mostly on the street, but want to be able to take to the strip. Did this motor come out with cast or what materials were used internally, any one know?
