Junkyard GT40 Heads & Intake upgrade for your Foxbody Mustang 5.0

On this episode I showcase the Junkyard GT40 cylinder heads and upper/lower intake I recently acquired. In this video I discuss the big differences between stock Fox body mustang 5.0 H.O heads and intakes vs. the GT40 Explorer/Mountaineer upgraded heads and intakes. These parts are the start 90's nostalgia tops end engine build I will be performing on my 1991 Foxbody GT Convertible.

I did this upgrade a couple years ago. I milled .040 off the heads to bring up the compression and Alex's springs. I hand ported the explorer lower to my heads. A small comp cam and it ran really really good. Oh and a bama chip to help with low speed drivability.

This video brings back memories. I think of the time I met a guy in a parking lot in the middle of the night to buy a pair of F3ZE (SVT Cobra) heads. It was like making a drug deal. A few weeks later I found the matching '93 Cobra manifold lying in the mud at a swap meet. I paid $500 (US) for the heads complete with factory roller rockers and $200 for the intake with gaskets and hardware. Man, those were the days. I still have the intake, but now it's bolted to a set of AFR 165s.

[@KASLCustoms]

Hahahaha that’s awesome. Been there too pal 😂👊

[@alertgasper]

i had one of those meets once--right down the street from a well-lit mall extravaganza, the seller wanted to meet me in a sketchy, barely lit commuter parking lot i drove by twice since it was hidden by a gas station and some woods...but i got a good deal on the parts, so oh well. another seller led me through a garage that was a recent extension to his house, down a staircase into his basement and after the deal was made, handed me a pamphlet about Jesus and asked me if I knew where I was going after the Rapture. "um, i'm pretty sure where i'm going 3 minutes from now..." all i need i guess is a seller who tries to sell me Amway. but the coolest buy was at a garage made from cinderblocks, two stories high. Waiting for the owner to come back to make the sale, I spot 6 foot tall concert speakers on the roof of his office, and his coworker asks if I've heard the latest Metallica album made with a symphony orchestra. there was some interesting accoustics there....

Hi Gary. I was listening to one of your somewhat older podcasts and you spoke of the Ford 427 SOHC engine, popularly known as the "sock" engine. NASCAR did ban that engine, but NHRA did not and it was very successful in drag racing. Chris at TIP said he has a pic of the engine with gear drive cams. I've never heard of that version, but the engine Ford released to the public was chain drive. Initially, the engine was released with sodium filled exhaust valves which, over time, would corrode the valves from the inside out, thereby causing the heads of the valves to snap off. Yeah, you can imagine the carnage that produced. Stainless steel valves solved the problem. In the late '60s, Ford sold quite a few Cammer engines and they're not terribly uncommon. I've seen a few in different cars at shows and other get togethers, and let me tell you, when you see one, it stops you in your tracks. For us old school car guys, it's probably the coolest engine Ford ever made. Anyway, as always, thanks. Bill

Hey man just stumbled onto your channel im enjoying it so much. I have been working a little bit on my 1991 mustang and was wondering if you think it would be worth putting 10k into some rust work and a paint job. It's a 1991 5.0L LX coop. My grand father was the first owner and then he gave it to me. It is almost 100 stock, the only thing we did was replace the exaught piping due to rust as it is a Canadian car. Grandpa bought it here in Canada new. It also needs interior work probably replace it all. The engine has 200,000 km/ 123,000 miles on it put grandpa treated it very well it still runs and sounds great. Do you think I should do the paint and interior work on it. And again it has nothing done to it all serial numbers match I'm second owner. Looking forward to hear from you and if I did all that work do you have a rough estimate what it would be worth? I'm not looking to sell it, like you it was my first car and I love her so much. Thanks

Hey buddy! Thanks so much for reaching out. That is an awesome story. Paint is a tough pill to swallow because of the costs involved these days… depending on how bad the paint/body is, I would almost consider leaving it and embracing it 🤷‍♂️.

I imagine Ford put the GT40 stuff on the Explorer because it weighs over 1000 lbs more than a Mustang and knew it needed a little more power. Pluse, without the extra HP, it probably didn't make enough more power than the V-6 for anyone to justify paying for the V-8 option.

My Fox came with the whole GT40 head/intake deal with a CAI and headers, I measured the cam and it appears to be an E303, it also came with a set of the 1.7:1 crane cobra rockers. I'm running 19lb bosch injectors with a Walboro 155 and a stock A9L. Is there anything in that setup you think I'm leaving power on the table with? Seat of the pants I'm gonna guess it's making 270-280 at the tires which is a ton of fun but I'd love to break the 300 barrier without having to build a short block. Can you tune a stock A9L for bigger injectors? I'm new to the Fox community so I'm trying to learn as much about my car as I can.

[@KASLCustoms]

Yes you most definitely can tune an A9L to do pretty much what ever you want it to other then run and very high rpm’s (i.e. 7200+). I have a video on my channel talking about this. Unless that GT40 set up is ported fairly extensively, I’m not sure that you would be that high in the HP department should you test it on the rollers. I also think you’re probably at the higher side of the duty cycle for the 19# injectors. That said, I would look at bigger injectors (24#) and a good tune and I bet you can find some “free HP” for sure 👍

@@KASLCustoms I wasn't planning on running 19's forever, just wanted to get the car on the road and out of my Dad's basement 😂. It sat for a long time before I got it but it didn't even have an A9L when I got it (somebody tried to do a MAF conversion with an '87 ECM), so I thought they'd be safe and good enough to get the car on the road for a summer.

Oh wow you don’t hear of that conversion wry often lol! In all honesty, I would seek assistance from a reputable that is local - or close to you so they can see the car and help you with the tuning.

The explorer upper is the heaviest of all the gt40 uppers.

[@KASLCustoms]

Do you know by how much? I’m genuinely curious as I’ve never weighed them. I would assume the tubular upper would be the lightest

[@jucedcustoms2274]

@@KASLCustoms neo mustangs has a video comparing the three. He has the weights on there as well.

Oh nice ok I’ll have a look. Thx bud 👊

[@jucedcustoms2274]

I have a cobra and a tubular. I’ll weigh them and report back.

[@KASLCustoms]

Ok thx bud! I’m very interested

[@86whitepony]

The reason why the Exploder had them is Ford made an overrun on Cobra motors. They used them to dump inventory on cars

[@KASLCustoms]

Oh really? That’s super cool

[@SaltySigma]

That's not accurate!! Who told you that?? Every single part for the Cobras and Explorers all have different part #s casted into them for their designated years and applications. The Cobra GT40 setup got 1.7 roller rockers and kept the High Output cam for more performance, while the Explorer GT40 setup had 1.6 rockers and a low end cam better suited for towing the extra weight of an SUV. All the heads had casting IDs as well. Just because the inside of the GT40 ports are all the same n flow the same amount of air at the same velocity, doesn't mean they are the same, even the F150 Lightings with a 351 got a GT40 setup that was the same, but different... Right off the bat, at 1st glance, all the intakes even look different, how could you even come to your conclusion?? It's not like Ford just happened to have MILLIONS of extra Cobra heads n intakes just laying around and some guy tripped over them and landed head 1st into an Explorer hood and had a light bulb go off! Tip Of The Day:. If you're going to tell somebody something, AT LEAST know what you're talking about!

Actually people who wanted to go fast back in the 80's and 90's didn't go with the GT40 Heads. The only people who used GT40 heads we're old dudes(to brag at car shows) who had too much money and didn't know any better. They were overpriced at the time($800.00/pair), and compared to the very popular World products, Edelbrock, and Trick Flow(heads found under the hoods of street racing and, track cars) offerings in the same price range GT40 Heads didn't make sense. Some people bought the GT40X aluminum heads. Those were a different story. Although the GT40 intake was always very popular! However the reason why GT40 parts are popular today is they can be had CHEAP! I think the explorer got the upgraded head from piled up old stock. Ford was good for that. All the GT40 head that didn't sell and they had no more E7 supplies.

[@KASLCustoms]

Interesting info. Around where I grew up the GT40 stuff was always the bargain “go fast” parts because you could pick them up at a junk yard for under $100. These days they are getting harder to find so therefore demand goes up which in turn drives up the price.

[@keithbusch4014]

Spark plug wires will burn up with the gt40P heads with some headers. If you could find some old world products Jr's or Sr heads you will run circles around the P heads.

explorers got the horse power upgrades because the vehicle was heavy and without drove like a dog.

[@neilbrown82]

Wait you're mystified as to why Explorer got those because it was an outdated engine making anemic power and Ford had those in the parts bin

[@neilbrown82]

A lot of work for less than 300hp bet it will include a letter cam 😅

Yep and less than$500 for everything including new gaskets. Can be done easily in a weekend 🤦🏽‍♂️ not everyone wants a race car.

@@KASLCustoms I made it ABUNDANTLY clear I didn't want the finish altered since I want a factory look. Didn't pay for that either yet Matt blasted this piss out of it and Tom was a real dick about it. Cost me an extra $40US to have it bead blasted to restore the correct factory finish.

Please don’t send that intake to Tmoss. Him and his son are a joke nowadays and do sub par work. Send it to big doggs, great people and they do amazing work.

[@KASLCustoms]

Oh wow really? I had a really good experience with Tmoss…🤷‍♂️. All that said, I have also heard great things about Big Doggs recently. All that said, I may look to use a local shop because with the way shipping is these days, I may never see my parts again…🤦‍♂️😔

[@TanCalHan]

@@KASLCustoms right, from what I’ve been told and can tell, tmoss did good work back in the day but nowadays hasn’t been up to snuff. Big doggs has videos on their page about the subpar work his customers have received from tmoss and he shows the porting process and the cfm difference. He has a flow bench, pretty cool stuff. But yea shipping sucks in todays world. UPS “lost” my original HO intake a few months ago.
