bigred, yes, you can just enlarge the exhaust side of the e7's and see a gain, most likely, some new springs, and just a little work on the exhaust side would be a kick in power imo.
torque Boxes= Where your lower control arm's bolt onto the frame, there is some thin metal there holding it together, look underside/inside of your rear wheel, i thought id inspect mine one day since im launching on stickies, sure enough, one is tearing, But it is repairable as of now, any more could be costly repair work.
Oh, I seen ported e7's (stock valve) and b-cam go 106 mph in a 3100 lb car, was a carbed car though.
