Ford racing Nascar heads.. 1200 bucks when we all buy just as expensive AFR's and trickflows.. yet we could get them suckers that the nascar guys use and get high horsepower with em.. good till 9k to lol

Dunno, would be interesting to see it work on a 5.0 gt

 

[GT89Mustang]

Umm maybe cuz its 1200 each, or because there would be zero low end tq.

...thats 2400 for a set of heads!! Although I would like to see some dyno #'s on those things!

*Not legal for sale or use on pollution-controlled motor vehicles.

This is why...

 

[poneypower89]

This is why...

Yeah, except my state doesnt control anything related to pollution crap on cars.

Plus there would be nothing on the low end!

Excuse my ignorance ...... why is this?

What size comb. chambers do they have?

Sounds like a good candidate for a Messican block with a screw type blower at around .... oh ...... 20 psi.

Those heads come completely unfinished. You need to do more work to them, valves, springs, studs, machining etc... the runners are also arranged differently so their might be a problem with your header fitment.

After you're done with these heads you would've put 10 grand into them, but hell of a set i tell ya!!!

LOOK AT THE INTAKE FLOW NUMBERS!! 400 CFM HOLY ****!!

I'd think the cam would have more to do with bottom end then the heads would.

...pardon my stupidity...I believe I was wrong on this one...after a little research I realized that the cam will have a great affect on low end than the heads will I guess I also made the assumption that they wouldnt have any low end based on the "Nascar" name...I guess because they are always running on top end....idk it was a stupid comment and I apologize...

pardoned lol

 

[SeventyMach1]

Well, I can see how you thought that. And I guess it's true to a certain extent. But, by no means should they be considered weak on the lower end. Granted, they could do better. I travel around the state with the NCARNG for shows..... I sport a HIGHLY MODIFIED Hummvee ...... and occasionally a Greg Biffle car that won 2 races. I asked the Docupak representative about this very subject. He says their gearing is what makes people think that. But like I said, it would still be awesome to slap a nice blower on an engine with those heads.......

 

[Lyncher]

I thank you all for pardoning me lol yeah I would definatly like to see some dyno #'s with those heads, then another 1 with thsoe heads and a turbo

 

[Thenemesis]

right under that is a set of Yates racing heads.. that are already done.. i didnt have the guts to check those out lol

 

[Lyncher]

the yates are the same price...check out the ford GT heads...they are the final revision of the 2000 Cobra R heads...1,500$ a piece... thats 3grand for heads!!!!

 

[maverick0716]

Those kind of heads are meant to be run at 9000 rpm.......do you guys have street V8 motors that run that high? Didn't think so, lol.

 

[Foxfan88]

omg the chambers on those things are TINY
