Stock head and Intake Porting

GizmosMustang · January 8th, 2006, 02:48 PM

ok how much horsepower can be gain by porting the stock heads and stock intake? and adding the ford racing e cam?

Twist 2 Go · January 8th, 2006, 03:32 PM

I'd say 50-60 depending on how well the heads flow afterwards.

GizmosMustang · January 8th, 2006, 03:33 PM

ok that sounds good how about if i stroke the motor to a 347 how much power will be gained over the stock motor?

Twist 2 Go · January 8th, 2006, 08:53 PM

you gonna need more than a e-cam for a 347

GizmosMustang · January 8th, 2006, 08:54 PM

Trash the intake. The heads can be made to flow OK, but the intake won't. Really, it's not a flow problem with the intake, it's the runner design and that the intake is built to perform under 4500 rpm. Your gonna need an aftermarket intake to take advantage of higher RPM breathing or your entire package will suffer.

well what i'm looking for is more power but retaining a stock look

You'll be wasting a head porting if you keep the stock intake. I'm not sure what the hangup is for keeping it stock looking, if you absolutely insist on keeping the stock intake then spending some bank (more than what it would cost for a better aftermarket unit) you could have someone cut open the stock intake, shorten and work the runners, and weld it back.

GT-40 P heads GT-40 intake and you will be doing fine. stock heads have some small valves to begin with and a stroker is a lot of money for a small power boost.

You will gain more from a good set of heads. E7s ported or not will be your bottle neck especially with more cubic inches. Stick the money into a good set of aftermarket heads such as a set of Twisted Wedges. Good heads are the key to making good power. Even the best ported E7s don't flow as good as a good aftermarket head.

The hang up is this Car is an SSP I wanna keep a Stock appearance because of show quality and everything if i can gain horse power with out going into more expensive heads and intake that don't look stock. i want as much power as possible with stock components like the heads and intake but the stock block will remain in the car for now but maybe in about a year or two and then will be pulled for a new sportsman block from ford racing So as of now I want as much power out of the stock block and components as possible.Thats the hang up with me buying a whole new intake and heads!

You can use GT40P heads and a ported stock upper/lower intake. The port3eds tock intkae when properly done can flow 190-200cfm which is a great match to the P heads. Power should be 260-280RWHP if a good cam is installed.

upgrade to the fox cobra intake i believe that was the only diffrence between the stock 5.0 and the cobra 5.0
which had a 25 hp diffrence

GizmosMustang · January 5th, 2007, 11:29 AM

is there a type of paint i can buy to put o the heads to make them appear to be stock?

If it is a show car, and there are really Mustang freaks there, they will know no matter how much Kylon you spray. I think you need to decide to leave it alone or go for it.

Darrellx14 · January 5th, 2007, 01:02 PM

If i were in you're shoes, I'd build that bitch bad, and just keep all the factory components incase you ever wanted to put the engine back to stock to keep the SSP value so to speak. Doesn't that sound like an idea?

GizmosMustang · January 5th, 2007, 01:19 PM

thought about that and might end up doing it

95opal · January 5th, 2007, 02:40 PM

If you really want to keep it stock looking and dont mind wasteing a few bucks.(JMHO) Then have the e7s ported http://www.thumperoforangepark.com/ and get in touch w/ Tmoss at http://www.tmossporting.com/ to have the intake done. With a well matched cam youll be looking at a nice power increase and still retain the stock look. The big ? is will this satisfy your HP Quest? Trying to keep all the stock parts for looks is going to limit your HP potential.

I have a set of early 351w heads that are ported & polished with 1.94/1.60 valves I would sell you. They have 60cc chambers.

notsoslo5.0 · January 5th, 2007, 04:53 PM
