I just got done building my motor. I was wondering how much hp I will have. I don't have a tune yet but I will get one as soon as I can afford it. I have a 347 stroker, afr 185heads, huge comp cam, roller rockers,all forged internals,comp cam lifters, trickflow upper and lower intake, bbk tb, 36lb injecters, sn95 rails,and a vortec supercharger with intercooler putting 10 pounds I boost I want to know roughly how much hp untuned and with a tune. Any info will help

I would guess you'd run out of fuel at 450rwhp. 36lb injectors aren't gonna cut it....

S trim vortec. I know I know i need 42lb injectors but moneys short now and I had 36lb allready. That will be my next thing and then a tune. U think the motor will be cool for now? Anyone know someone with used 42s for cheap or trade

36# injectors are not nearly enough fuel supply for a 347 on 10psi, at minimum u will need 42#'s and a new matching calibrated mass air flow sensor to match the injectors.. unless ur running a standalone with a blowthru maf.? Also I hope its not the stock fuel pump in there cuz that wont last long under those conditions.. u at least need a 255/lph [ 2013-06-26, 09:34 AM: Message edited by: Charged50 ]
