Fuel Questions

[TeufelGt]

All you fuel system savvy guys i needs some information.

Ok so heres the deal i'm moving ahead with my build. Got a Tork tech blower installed already for the last year...Stepping up (or down i should say) to a 2.75 pulley. The blocked is being filled with forged manley goods. Cams are Stage 2.5 CMS...and heads are going to be ported.

So heres the question. I have an 03-04 cobra tank and dual pumps being installed. The injectors I have are the 42 pounders that come with the Tork Tech kit...Car made 409 and i'm going to up the boost with this built bottom. Do i need to step up to 60 lb injectors and if soooo do they fit stock fuel rails?

Ok guys lay it on me...(No homo)

I would not run stock rails on anything over 400 at the wheels, even if u can get by with them its not a got idea, also a good regulator, as for injectors i had 42lb and lost fuel at 450rwhp but some say they have got more, i have 60lb now and have been up to 672rwhp on race gas at 18lbs of boost, hope my trial and error helps.
