needs fatter cams... you can really make impressive gains with more duration. You never have to worry about PTV either so you can get bigger lift too. It's worth it in spades on the 3v. I'm betting you see a 15hp or better gain from cutting the runners down to 11". Show some intake pics or I'll e-choke you. hehe. How exactly did you get 7" cut out .... hmmmmm.
Hurry up... I gotta see this setup.
