huh?
They might be Ps or standard GT40's... the whole motor is a good buy if you can get it...The exhuast manifolds wouldn't be used in your car....Builder/Owner of Badass Panther Wagons

It was a mountaineer, i'm pretty sure there GT40P's and i was told that i had to use the factory manifolds because of the way the plugs are, is that rightLast edited by Bowman85merc; 05-20-2008, 10:31 PM.---1990 Lincon LSC., 5.0 H.O., 55,000 ORIG. miles, 3:73 Posi, Bullit rims, 3G alt., 2.5" full-back exhaust, Mark 8 elec. fan, Flowmaster mufflers.

You need the FRPP headers. You'd have a total nightmare of a time getting exhaust made to work on those factory manifolds. They're also quite simply horrible, and would go a long way toward negating any gains you get from the heads.86 Lincoln Town Car (Galactica).

Any Explorer/Mountaineer head is an upgrade over what you've got. It's easy to tell the "P" heads from non-Ps, as they have four ridges on the ends of the heads and say "GTP" near the head bolts where the regular GT40s just say "GT". You do not want to reuse the Explorer exhaust manifolds, as they're highly restrictive. The Ford Racing headers referenced above will fit the "P" heads' unique spark plug angle but will have to be sourced from an aftermarket supplier such as Summit Racing.

If you're getting your heads ported you can get outstanding results with just an E7 - saves having to spend the extra bucks on a nominally more desirable core. Someone like turbo's pal Gerry in Canton, MI can hook you up for around 600 bucks total.
According to basic simulations and assuming an Explorer camshaft, you could make as much as 250-270hp with stock E7s, up to 300hp with GT40s, and maybe 330-plus hp with BHP-ported E7s. "P" heads are said not to simulate well with basic software, but they're supposed to be a decent jump over regular GT40s in real dyno testing.
If you're looking to make more serious hp, you might want to abandon factory cores and start looking at more radical aftermarket stuff. A serious race head like the AFR 225 shows over 400hp in my sims with the same Explorer camshaft or around 480hp with a Mustang cam and single-plane intake.Last edited by 1987cp; 05-20-2008, 11:16 PM.2012 Mazda5 Touring | Finally working on the LTD again!

headers, FRPP headers, they're aftermarket exhaust parts. Not factory heads. I'd go with P heads and do the exhaust, you'll get much better results than using ported E7 heads and a factory exhaust. If you're gonna hot rod the motor, its gotta be able to breathe86 Lincoln Town Car (Galactica).

Yep, the BHPs would be just like the ported E7s Mr Land Yacht has on his car. I've ridden in the car, and it's impressive to say the least. Pulls strong to 6 grand, too.
P heads would be the way to go for sure if no porting were planned. I've not seen much info on how they respond to porting, though. You might PM turbo about that, though.2012 Mazda5 Touring | Finally working on the LTD again!

If you already have piping to fit regular Mustang headers, you're all set as far as the exhaust system is concerned.2012 Mazda5 Touring | Finally working on the LTD again!

Good headers are a bonus anyway. I have cheap Hedman headers on my car, got them used and I had to get them milled flat so they would quit blowing gaskets. They're also sort of a pain in the ass to install, some of the bolts are hard to access. If I'd spent more and gotten a better quality header to start with, I wouldn't have had those problems.86 Lincoln Town Car (Galactica).
