i have a 5.0L and i want 300rwhp. i want to keep the stock shortblock
what should i buy?

25thmustang · Mar 14, 2006

AFR or TFS heads, Ebrock or TFS intake, matched cam, and all the bolt ons. Should be easy 300 rwhp!

Orrrrrrr,buy a Blowzilla SC an after market mid pipe with high flow cats and your good to go!!

A question like that will bring out an answer as accurate as your average joe throwing darts. The general consensus with a full HCI combination (with moderately-matched streetable components) yield output in the 300-350 fwhp range.

+1. Its hard to tell just what you will get as it depends on many more variables such as engine attributes i.e. mileage, break in.... I would say you would be real close to 300whp though.

If your on a budget I would go with the GT-40 setup you were talking about in the other thread. GT40 heads, intake, 70mm tb, 1.6RR, and an E-cam should get you to about 300 and it wont break your bank. If money is not an issue go with AFR deffinately with a custom ground cam.

I'd say just get a small vortech, with somewhere around 14 PSI. That should be right near 300.

8psi gives you about 100 HP to the wheels.So 14 would give him alot more.But stock heads and intake will severly choke his potential!!

Go to AFR's websight WWW.airflowresearch.com

There are aticles on combos with the 165 heads. 400fw hp should be a piece of cake with the 165's and a mild cam

There is actually an article there where they make 400fw hp and over 350 ft-lbs of torque from 3500rpm up on a used (completely stock) 5.0L and that's with the stock cam using out of the box AFR 165's with a CR of 9.0:1

Check out the articles

Even if you were to lose a very conservative 20% HP through the drivetrain and whatever you run off the crank, you're still looking at over 300hp to the wheels.

I'm gonna go with recommending a 150 wet shot... Pick your brand of nitrous.

Or you can do it the expensive way I did (AFR165s, Ported Cobra, Custom Cam (FTI), 1 5/8 longtubes, o/r H-pipe, and all the other basic bolt-ons.

Good luck however you try it.

i was thinking of buying the trickflow top end kit and selling the intake because being a truck i need the low end torque but i might just go with the mix and mach combo that i stated before

i dont want to use nitrous

i was looking for a simple way to get maximum hp out of some bolt-ons. wich ones are the best and what is everyone else doing to beaf up their foxes.

You also lose power thru accessories too...that was also with a carb, on just an engine dyno. Those numbers aren't anything special...

I did 304hp/339tq years ago with the TFS combo, full accessories, shorty headers, 76mm maf and a 65mm tb. It needed LT's and a 75mm tb but still over 300rwhp none the less in 90*+ summer heat and humidity.

killrb · Mar 15, 2006

I did 322 rwhp with Ed Curtis (FTI) cam and AFR 165 heads, GT-40 with ported lower, 24lb inj, shorty headers, x-pipe, C&L 76mm, 65mm TB, and pullies. This was thru a 5 speed on a Dynojet. In all honestly, there was still another 5 hp to be had once I found a couple little problems with the MAF and a cold air intake I made. Anyway, it ran good.

Yes, that's why I sugessted somewhere around 14, being the stock intake, head, and cam will restrict it. Gosh

killrb - What accessories did you not have?

powermaxx · Mar 18, 2006

what type of fuel pump do you run with that hp ?

what type of ignition do i run?

anyone breaking 12s with 320rwhp?

ddonaca351 · Mar 18, 2006

Trick flow track heat h/c/i package, good exhaust system, MAF & 24# injectors, 65-70mm TB, and a decent tune should get you 300 at the wheels.

Also depending on which dyno you go to you can get 300whp with only 260-270hp... lol.
