I was looking on the web and was told to multiply my flywheel HP by .38 to get the fuel pump size I need. I defenently know my car should be around 300hp, so my pump is lacking if it can only handle 250hp. I know its not my cam even though it is stock.

seriously...1... put a cam in it... that WILL help

and uh yea upgrade your fuel system, wtf

You thinking 300 to the wheels or at the fly?

nitrous_bob

it's the timing

the stock fuel system (if it is working properly) will support well over 300 hp, 325 for sure maybe closer to 350

FWIW, the info I posted above from the Ford Racing catalog doesn't support that.

those 185 afr heads flow alot more air in there and you have bigger maf bigger TB im thinking you need a tuner or tune

get the 255 pumpbut I dont think thats your problem

I think you just have way more air than gas going into your motor with that stock maf setting and no tune

just my opinion....

This is one of those questions, where the solution is stated in the question. Get a timing gun at autozone for $20 or hae a shop set it.

Ill give you a hint, I set my timing by EAR, when I checked it, spout out gun on one, I was at 0*.

My car ran fine at that until I got to 4000 rpms and it seems like I lost fuel.

Set your timing to 14-16*, and go from there.
