I never ever said that I know all,...what I am saying is that my car runs better and idles smoother. You, Vortech347 are being very arrogant in saying that the process is a waste of time and money ; the mere accusation that I am imagining the better acceleration and performance reinforces my belief that your are in fact an over overly opinionated want to be know it all. I have done a visual inspection of a 5.0 F/I Edelbrock Intake, the amount of varnish and gunk removed was significant!!! I will trust my own eyes and seat of the pants feel over your bore scope any day of the week.It doesn't take a rocket scientist to know that a car with a clean t/b and intake will have a zippier feel to it. SORRY IF I MADE YOUR WEENIE FEEL SMALL BY MENTIONING MY OTHER CAR,...I kinda used to that though,...I am a bro you know!!! As far as my stang,...it way more than a crate engine in a car. Alot of people have done it,...but not alot are as quick as mine,...ie suspension, tune, driving.
