It won't work. You'll need to rip off the stock intake and bore it out or get a new intake for the 2" bore to work. I wouldn't bother and I really don't have time to go into detail. All I'll say is do a search for 670 2" TBI holley and all that jazz. There are a lot of good posts that explane that the 1 11/16" stock TBI is good for 300hp.

the truck intake is also 1 11/16" throttle bores.. apparently the holley tbi unit comes with some kind of tapered plate that goes from the 2" to 1 11/16".. I don't know if this is of any advantage though and therefore I have never bothered to replace mine.

you dont need it nor want it until you have passed the 230hp mark. it wont help unless you are burning your own chips as well
