I used 190cc aluminum heads on my 2000 explorer 5.0 along with a TFS stage 1 cam and OBX headers. Those wondering: 2.02” intake valves clear stock ‘00 explorer pistons with the TFS stage 1 cam (.512 lift on intake). Running the factory EFI still just had to turn up the idle to about 800. Moves my 8” lifted ranger on 33s pretty well!

[@KingJT80]

That's good to hear. I have the stock 79 bottom end in my zephyr that has Pistons with no notch in them like 86 GTs but I've heard those guys have no issues with stage 1 cams and 170 trick flows or the newer 11R heads either so i think that's the route I'll go

[@skipgumphrey9579]

Jay you mentioned the .512 intake lift while discussing valve clearance with your TFS 1 cam, but TrickFlow lists the specs for that cam as .499/.510 The only way I could imagine you getting.512 on the intake side would’ve been if you’d used 1.7 rockers instead of the stock 1.6…

[@danielwilson6665]

Paul the canted valve Cleveland 2-V production iron heads will easily outflow E7 heads (and most OEM Windsor based heads) while still maintaining decent charge velocity across a wide rpm range with the 2-V sized ports. The only thing to be aware of are the negative comments posted by the clueless online experts in regards to the open combustion chamber design produced for U.S. vehicles. While it is more prone to detonation than the excellent OEM Cleveland 4-V closed (quench) chamber design, the problem can be avoided with the proper compression ratio, cam duration and ignition timing. There are still plenty of 351C, 2-V heads available in salvage yards and online at affordable prices along with a good selection of aftermarket “Clevor “ intakes and/or spacer plates to adapt Cleveland heads to 8.2” and 9.5” deck height Windsor blocks. All blocks will fail when their power capacity is exceeded so anyone overly concerned with the cyber hype about 302 blocks splitting in half when pushed hard should just use a Cleveland block to start with. It doesn’t matter if it’s the 2 or 4-bolt main bearing cap variety. They both have stout bulkheads and pan rails supporting the bottom end. Seeing is believing so check out the DragBoss videos right here on KZbin. His naturally aspirated, single 4-V carb, all engine 408 Cleveland small block stroker pulls 752 horsepower on the dyno, runs 9.60 quarter miles in his all steel ‘69 Cougar and he has been using the same OEM 2-bolt main iron block for almost 20 years with no failures. Try that with a stock Windsor block or even a highly overrated SBC block and you might have a very bad day. Lots of builders like yourself have had great results with standard displacement as well as larger 383”, 393” and 408” Clevor strokers. If anyone reading this has doubts about the power potential of Cleveland heads, I suggest checking out “The Other Guys” videos featuring Cleveland heads posted by Mr. Holdener. His fair and balanced method of collecting real data and posting the results regardless of the outcome is as good as it gets in the cyber world tainted by bullshit 😉. And the beat goes on……

[@jackgtx440]

@Sub250 aerial shots that’s not exactly how it works. If the heads and/or carb is too big, the air velocity falls off and it makes less power.

[@jackgtx440]

@Sub250 aerial shots right, being an air pump, to flow more air to accommodate big carbs and ports, you have to spin more rpm to pump more of said air. Most engines are limited in valve train and bottom end to spin 7, 8, 9,000 rpm. So adding these big ports and carbs would make less power and be less responsive when limited rpm is a factor.

[@jackgtx440]

@Sub250 aerial shots I think we’re actually agreeing and just debating because it’s the Internet. I too have been class racing for years. Over carbureting an engine might not make less peak power, but in lower speed applications like a street car it will certainly have a negative affect on the usable power and usable rpm of the car. If the carb doesn’t have enough vacuum at given RPM none of the circuits are going to work correctly.

Chevy Keith black pistons, I cut the top of pistons to fit Valve reliefs. Boss 302 heads and stock intake. Cleveland headers. 800 double pumper for sport driving, just a 600 for street. With the stock roller cam engine runs smooth and off idle torque is great. Believe it or not. With double springs, engine will pull to 8,000 rpm. You could use Cleveland heads. I have a pair of 71 boss 351 heads already to modified for another clevor. A wedge head does make a bit more torque on low end. But pound for pound nothing beats a clevor for a head rush.

What intake and carb is that? What spacer as well do you recommend? Also, what cam would work well in a 302 and later, in a 351? Would that 274 work well in both?

[@richardholdener1727]

afr heads, 274 comp cam

[@Gkitchens1]

I don’t need power I’m perfectly happy with a stock engine cuz I only care about low end power and sound. You know light to light power is all I want. Want a cam that sounds really good but doesn’t completely rob the entire bottom end power band. Most anything you do takes away from the bottom end. So I guess to get what I want I just need to pick a cam and put 410s in the damn car?

Big question ⁉️. I have Edelbrock performer heads (non RPM) have you worked with them before they say 190Cc. I'm just trying to ball park my hp. I have B Cam 1.7rr shorties and Ford Single plane Intake

Hi Richard i have a Mustang with an 86 motor in it, I’ve heard that e6 heads are no bueno as well as no other heads work with the flat top pistons used for that one year only. Am I better off to run new pistons that way I can utilize better heads?

Hi . Would i be better off rebuilding my 66 hp heads that need to be updated from leaded fuel . Or a set of gt40 heads . I now the gtp heads won't fit my car because of the plugs aren't angled. And the big thing is i have to stick to a budget, 2 kids in college put a damper on the money.

[@richardholdener1727]

GT40 WOULD BE MUCH BETTER THAN EARLY 66 HEADS

[@danielwilson6665]

Hi Michael, if your ‘66 HP heads are from the “K” code, 271 horsepower engine, you might be better off financially by selling them to a restorer for a correct restoration project. In my opinion, they don’t offer much of a performance advantage over standard 289 heads. Shop around for a reasonable seller with a decent set of GT40 heads that’s also trying to pay for his kids college tuition. It’s a win, win deal for all. Maybe when your children graduate and get high paying jobs, they will show their appreciation for the automotive sacrifices that you are making for them and buy you the crate engine of your choice 😉. Hey….it could happen !!!

Im looking into building up my mystery 86 5.0 mustang and like this combo but with junkyard heads and intake quite a bit. Will the stock injector size with the factory ECU work and give me similar gains? Or what size injector should I use and will i need to piggyback the ECU? Only mystery here is the guy who sold it to me said it had a stroker kit in it but i havent taken it apart to verify yet. Also have read that the 86 GT motors had no valve reliefs? Is this true in the event that it is stock? And if thats the case will i still be able to use GT40 heads with the XE 274 cam? Thanks and happy holidays!

I want to apologize in advance for any dumb questions. So......I'm sorry 😕 I'm a Chevy guy that do to circumstance has Fords. A 96 Explorer with a 5.0L and a 97 F-150 4.6 (VIN 6) 4x4. I've pretty much totally rebuilt the F150. Engine, Trans & Transfer, Rear diff, and totally replaced the interior (seats and center console out of an Expedition, dash, basically all the plastics), then a custom paint job. I know it's a lot. But the wife doesn't ask for much. So when she does, she's going to get everything she asked for that's within my capabilities. So my question is. Just how good are the heads on that 302 that's sitting in the Explorer? Same question also concerning the fuel injection? The trans in it is gone. Doesn't have Park anymore and the transfer case is shot. If I do anything with that engine, I'd like to land somewhere in the 400 to 500 HP range. Preferably without NOS. Boosted, maybe. Supercharger doesn't sound back. But for now just NA. Sorry so long winded and for some possibly dumb questions. Y'all be safe out there and keep the rubber side down 🤠😎

the heads on the explorer are 30-40 hp better than stock 5.0l heads. add a cam and boost and 500 hp is easy

Especially with swap ecus like a Holley Dominator, tuning efficiency can make old setups just as good as today’s from idle to redline. We’re then splitting hair between compression ratio and +-20HP.
