Roots blower and Tbi

IS anyone running one on this board? I have see a setup for the chevy trucks and was thinking of doing this in the next 6 months or so possibly.So far what im thinking is that i would need the truck ecm( for the chip that comes with the blower)Possble new fuel pump, new injectors and also a cowl hood. If im leaving anything out please let me know. Right now i have 55psi injectors i think.anyone who has done this swap info would be aprciated. p.s I have the Lo5 caprice engine in the rs currently what kinda numbers do u think this would put out in stock form. thanks guys.

shane B. had a vortec headed 350 wTBI running mid/low 13s and single plane intake. He put the blower on it and was running 11s but with a fat carb and lousy 8MPG. Your money would be better spent on non swirl port heads and a better cam than a blower. GM had non swirl port heads on their old 350 H.O. crate engine and was rated at 300HP. I think you should get these heads, a LT4 or ZZ4 cam and a single plane intake.

Thanks for the reply Tas, I have a cam and heads in the works. I was just trying to get some info as to what a baseline hp increase i could get without heads and cam. I'll probably have to contact the manufatur and ask, from what i hear the trucks had the Lo5 as well> I think I could expect better than 8mpg using tbi concidering this is a smog legal mod for the trucks. If anyone is interested let me know and i will post what i find out.
