Im thinikin about Getting rid of the stock Intake Manifold, and going with Edelbrocks RPM II Manifold. Ive heard nothing but good things and,and have heard upwards of a 40 Hp gain. Im wondering what needs to be done to support the extra hp. 24# Injectors, 76mm Maf, and a fuel pump? I already have a Aeromotive FPR. If someone could set me straight on what i need to do that would be great!

For the intake, your fuel system is fine. Stock fuel system will support up to about 320ish HP. I would get a larger throttlebody and larger MAF if anything.

That intake (without aftermaket heads) is really going to hurt your bottom end. It's a nice intake, but for supporting mods you will need a set of TW / Eddy / AFR heads to help deal with all the extra air that intake will breath into your motor.

Supporting mods:
MAF / TB / EGR
Maybe 24# injectors, probably not
Gaskets for the install

Plans down the road are Just like any other mustang Fan.....Stroked and blown. Which Manifold will be a good power adder and not hurt my bottom end? I Would like 50 More Safe hp. I plan on doin a BBK 70MM Tb and EGR, 24# Injectors, Bassani X-pipe, and a different Manifold for now....

I like Trick Flow intakes personally, so I'd suggest the Street Heat for your combination. The Edelbrock Performer, BBK SSI, GT40, Cobra, and Explorer intakes will work just as well.

I agree, you might loose some bottom end but will pick up at least a little horse and will be setting the scene for a much better set of heads. How about this, contact a member on here TMOSS and get your stock lower ported, take the rest of the money and put it in an envelope that says "Aftermarket alumimum heads" You will be able to sell the TMOSS lower for about what you paid for it so no loss.

So i should just wait until i can afford some Trick Flow TWH's, Cam, Rockers, Springs and supporting mods before the Manifold swap?

In the mean time what do u suggest i do to get these 5.0 Movin. As is ive run a best of 14.612 and best trap of 100.38.

Yes waiting would be smart and do it all at once. Get yourself a custom cam and thata combo will be a hard runner!

I would get some 373/410 gears for now.

the gears and x-pipe sound good but you might want to pass on the 70mm tb for now and just grab some headers instead.this way your exhaust is finished and your ready to concentrate on the intake side of things.

Go longtubes. If you're wondering about the guy saying the won't add power, then disregard my first statement.
