how much horsepower will some 93 cobra gt40 heads and gt40 intake be pushing on a 93 mustang

30ish

black05gt · March 10th, 2011, 06:18 PM

would it be worth trading some black 17x9 with a polished lip with good tires for some heads with roller rockers ready to put on

What are the rims worth? GT-40 parts are dirt cheap. You should be able to find a used set for $200 and an intake for $150 or less for both. You can find an entire explorer engine for around $350-$400 with GT-40 stuff on it and sell the shortblock to recoup some money and end up paying even less. Decent rims with good tires aren't a good trade at all.

you could probably find some gt40 heads for around 200-300, depending on how hard you search. I bought my gt40p heads ported, milled, and fresh springs for 300. So if you can sell those wheels for 600 or so you could buy some heads and supporting mods like a cam. IMO

yeah so im better of selling my rims separate then where can i find some heads to buy in houston

And the junkyard

black05gt · March 10th, 2011, 09:45 PM

other than the plugs what is the difrence in the p heads

ryanw · March 10th, 2011, 09:51 PM

I dont think the P heads have the smog ports on the back. im sure theirs other stuff, but im unsure of what they are. Im told the P heads are better then the regular gt40 ones

ESwanny11 · March 10th, 2011, 10:02 PM

you need to make sure you get headers that fit P heads. Not sure wwhich ones fit, but I'm sure someone will chime in and tell you. Because of the spark plug angle you run into some clearence issues

black05gt · March 10th, 2011, 10:37 PM

well if i have to get headers i might as well save the money and get better heads i want some longtubes that means i will also have to buy a mid pipe,and ive heard the non p are better

fogged306 · March 10th, 2011, 10:47 PM

The P heads will make more power. The plugs are centered more in the chamber for a more efficient burn. I believe the chambers are shaped differently too. That's why they're a pain with headers sometimes because they're not in the normal plug locations. I've never run them so I couldn't tell you first hand, but I've seen a lot of guys say you just need 90* boots and they work with most headers.. Either way, you've got the right idea about saving up for good heads, I'd stick with that plan.
