Ok....thanks for that. The other day when I had Sean on the phone, I was speaking about a "ram air" faux tank. He was working on a 1300 off to the side, and he is planning some IMPRESSIVE numbers out of it.
I'm used to working on BB Mopar....so I understand that HP isnt cheap.
And, by itself without swapping over the desired parts (mostly heads/cams) they don't put as much power out. But, with the head/cam swap complete you can expect an approx 10% Hp gain by doing the swap without any other mods at the same time.
