effective rpm range

It's a lot of intake and carb for a little engine and cam. I'd guess 3500-6500 with what you've given. With a proper sized 4bbl and modern dual plane, more like 2300-6000
believe it or not the t-ram has excellent low end with my current set up.i ran an air gap as well as an x-celerator before the t-ram.it has more low end than the weiand,and almost as much as the air gap.i expected the t-ram to have crappy low end,but(no lie) that is not the case.do you think this profile will be good for street use?
