gt40p in 1984 ranger /which headers will work

[85_Ranger4x4]

To the OP...

What numbers are you expecting to get out of your engine with what has been done to it? What all has been done to the engine? And why the choice of the gt40p heads then say the gt40 that only flow a few less CFMs a minute?

I have a buddy that has an explorer engine in his 2001 ranger that has the TM headers. He said they fit perfectly.

Personally if I was to have an engine built it wouldn't be wearing stock heads at all.

TM headers should fit an 01 perfectly, they are designed mainly for the 95-01 Explorers which are identical under the hood to a 98+ Ranger.

I have heard the old Mustang Ho-Po manifolds (essentially cast iron headers) work with the P heads and IMO they look like they would be pretty close to fitting in my truck. The angle of the passenger side may be a problem, hard to tell.

the majority of swaps i worked on were pull outs and generally used granada type manifolds...theres a straighter version of those that used to be easy to get for like 80-140 bux for a matched set new.....that or a combo of vic and 351 van or sn stuff. low hp setups dont need much.

and the majority of 302 swaps go that way thus the problem of being stuck with crappy swap headers.

the hi-po manifolds are not cheap to get new and are come and go on the auction site. i would use a mac/jba/bassani header and mod the rails before i spent more then 150 bux on manifolds. the granada manifolds are not as easy to get as they used to be either and are restrictive depending on style....they blow explorer stuff away imo though and the straighter type are easy to fit o2 sensors to if you have efi.

$260 isn't too terrible if they would fit.

Anyone thought about trying a set of the old "Hi-Po" headers? Some of the Mustang guys have been using them in their classics and the "P" heads. Mustang Unlimited has them for $260, look like they will clear the plugs. Not sure how they would fit the Ranger chassis.

I tried to find them on their website. I couldn't tolerate it (oddly setup) with the slow internet here at work...

260.....hey.

no problem for those....i usually see them around 400 a set....260 is reasonable, iirc they were good to nearly 350 hp on old iron heads.


150 for a granada setup vs 260 for those, i would go with them.

odd i never found new ones that cheap. hey..i do not know it all...

just the little bit i can fit in my tiny little mind

Not dreaming or thinking that I could buy a "professionally built" motor for 2 grand, but I wouldn't buy a built motor. I would build it my self, and do damn near as good of a job as that "professional builder" did at half the cost. If I were to buy a "professionally built" it damn sure wouldn't have GT40p heads on it and I'd expect to be spending alot more than 5 grand on it. Just because your paid 5 grand to have your motor built does not mean that it is a 5 grand motor, you may have 4 grand worth of labor into a grand worth of crap. Labor means nothing because what you could have preofessionally built in CA for $7,000 may cost me $5000 here in GA, similarly what I could buy on one side of the street for $5000 I may be able to get on the other side for $3000. Until you tell us what you actually have in the motor that dollar figure ain't saying shit.

No I have not built a 347, never intend to build a 347. Have I built a 302, no; have I built a motor, yes. Have I done alot of research into how/what to build and how to get it into an RBV platform, yes. I intend to build a forced induction 331 stroker, and with the components that forced induction will require I know that I will be spending more than I stated in my previous post. Never claimed to be an expert, but if you want expert advice and opinions the go payan expert for them.

What my useless whitty banter was trying to tell you is that I have a 302 engine with the same heads going into the same body style truck. The best fitting options are very overpriced if available TM headers, obsolete FMS headers, and factory explorer manifolds. That given what has been posted here in the past about your setup, your best option is the explorer manifolds. If blowing cash is what gets you off at night then by all means go buy some headers. Personally I put the header money someplace it matters, being able to stop.

josh t, so basically you have nothing useful to offer except your hypothetical " in theory" knowledge of absolutely nothing that pertains to my question! I am sure you would do this ,that or the other thing and I am sure you have built high performance engines and know all thats involved and the ins and outs of internal combustion but thats irrelevant. and do you think I dont realize that yes explorer manifolds may fit . why bother replying when you really have no clue there buddy. save all that high performance dreaming you do for the day when you can afford to actually build an engine instead of sitting on your computer giving ignorant unsolicited engine building advice which is all in theory. the more you try and sound knowledgeable its becoming very clear you have no idea what your talking about. sorry but you should have quit while you were ahead. and furthermore you may have the same brand engine (ford ) but i guarantee you that's the only thing your engine has in common with this particular engine.

advance adaptor headers . pass side fits great ,drivers side needs some minor modifications to clear plugs . band saw , tig welder couple small pieces of tubing and voila. headers 300 bucks and couple hours time. could be worse. still would have liked to use torque monsters but they dont return calls or emails or any form of communication once you place an order?dont know what is up with that but kinda frustrating

I realize how forums work

You can say you do and maybe even think you do but you don't have a clue.

even though you may think your opinion matters in this situation it really does not.

That is how forums work. You don't think JoshT (who has been working on his build for years) has done any research about what headers fit GT40P heads in a Ranger? Or that anybody else that hasn't done a swap specifically involving GT40P heads hasn't bumped into something in their searches? Or that a concern from a different setup doesn't cross over?

Personally researching my build I realized they are a PITA to find headers for and wrote them off before I painted myself in a corner as you did.

and furthermore you may have the same brand engine (ford ) but i guarantee you that's the only thing your engine has in common with this particular engine.

And that as ALL that matters. At the end of the day as long as he has a similar block (even a 289) and the same heads it does not matter a lick what he has for an engine. As far as fitment goes the headers will not care one bit what if anything is inside the block.

You were given good answers by good guys and spit in their face as a reward. What a guy.

i spit in your face ? how does me getting your unsolicited opinion on all the parts that should have been used and would be used if it were you doing a build when you have no clue how or what it takes to properly build an engine that not only is efficient but is reliable. the amount of money and the parts used is irrelevant to my question and yet you seam to think you have some knowledge that really you do not and furthermore i would not even bother wasting your breath talking because if you were as knowledgeable as you think you would be building engines not sitting on your computer talking about it. you should go work for ford racing as an engineer and show them how its done. I bet they would love to have someone with your expertise show them what their engineers have been doing wrong. i get a kick out of some people that think that these aftermarket companies have a fraction of the money to spend on research and development as say ford does! you think that horsepower is just bolted on and thats it? like the guy who gets 650 hp out of a naturally aspirated 302 that he built in his garage !i gotta laugh at the bullshit i have read on this forum. get a life

fyi ford gt40p heads can (with the proper valve job ,springs ,porting,reshaping and machining) flow more air and seal up more efficiently than almost any aftermarket aluminum head except for a select few that cost over 2000 dollars and are aluminum , which is not the best choice for reliability when mating to cast iron and cast iron under stress is far superior to aluminum. for race car engines ,yes aluminum works great. the engineers at ford are not idiots and they have far more money to put into research and development than any of the aftermarket companies making inferior aftermarket parts. nothing aftermarket fits like factory. before you go believing what you read look at the results on a flow bench and you will see that properly machined and reworked gt40p heads will flow more cfm than aftermarket and 90% of the after market heads dont flow the cfm they claim . they may weigh less than cast but who cares about the weight unless your building a dragster. all i am looking at is efficiency of the valve train geometry and how much air they can move (cfm) thats what makes reliable horsepower. its easy to believe what you read in a magazine but a flow bench does not lie nor does the dyno.

Puff, puff, pass.

If there is so much BS on this site, then why did you even bother to ask a question here just to shoot them down?

Some of its built our vehicles on a budget, some, there is none. I don't see your 302 RBV yet so as far as talk about us not knowing what we are doing...you wouldn't have asked us if we hadn't done it.

More where did you get your stats saying a gt40p had will out flow 90% of the after market heads? Not saying it's not true, but I didn't see you say you have hands on experience either, maybe a buddy told you. Also for going as custom on an engine, why buy headers, they are a bolt on performance helper. No experience to thus point, what's stopping you from learning, the easy way out?

Sorry you asked us and we gave our help and answers based on what we know and we have done.
