I wouldn't put the Holley on a 302 at all. Works great on my 347 and AFR 185's but on E7's with a stock cam its a total wasted. Wait for more cubes. Edelbrock Performer is a great 302 intake and when more mods are added then change the upper to an RPM. Right now stick to the basics-Gears, Exhaust, Pulleys, Subframes, etc.
