I would go with the edlebrock 650, electice chock and the performer intake, if torque is the goal, the RPM will be a bad choice until the upper revs. over 1500 and will really pull at over about 3000. I have a mild build 350, 9:1, mild cam ( forget the numbers) and she breathes really well, HP is about 300 and it is a great driver, and highway machine (consistently at 15mpg) good for an aerodynamic shoebox. most folks I spoke to before choosing the setup, said it is common to over carb a motor, by the time you jet it down to idle and run right, it is a waste. the 650 was a piece of cake to set up and doesn't require tweaking at all. set and forget it. that is my two cents, everyone has opinions. later
