gt40p in 1984 ranger /which headers will work

[green lantern]

I need to know which headers will definitely work in a 84 ranger 4x4 5.0 roller motor , gt40P heads ,without interference. I have a c4 trans and stock transfer case, no a/c and no emissions. I need info from someone that has actually seen or done this before . no guessing please

Well I am in the process of doing the 5.0 swap on my 84 Bronco II and the heads on my 5.0 are the GT40P heads and I can say that I tried 4 diffenent sets of headers before I said screw it and built my own. One of my biggest problems other than the P heads is I am using a AOD tranny which takes up a lot of space, my Bronco II has been changed over to a 2 wheel drive street truck so that helped me on my drivers side header, I will post up pictures of my headers in the next couple of days. One set that I did not try was the fox body mustang P headers but from what I seen from the non P headders they hit the frame rail on the right side.

Unless you have your engine mounted like someone else to use a particular header then everything is a guess. Unless you pony up the cash for a set of torque monster headers you are most likely going to do some trial and error. Some headers will fit around the plugs if you use 90 degree boots but that doesn't mean they will fit in the truck. Seach the site some have used different ones with different degrees of success. If you don't have a wild engine use the factory 5.0 explorer ones.

does anyone know if the torque monster headers are a guaranteed fit ? if they are then the cost is not an obstacle. I dont want to buy them if its a guessing game.

Best to talk directly to torquemonster.

they fit fine...just dont hard mount your engine till they are installed on it. get them on there and put it where it works best for you


its a great product but hard to put 700 dollar headers on a 300 dollar engine


many start out with normal 302's and mustang and explorer 302's are normal to me...150 and vic engines make me puke.

but eventually the upgrades come...so a worthy investment to the dedicated sbf guy.

if i were to do a gas v8 swap for myself these days it would be the newest low mile ls type engine complete powertrain i could afford..

 

[85_Ranger4x4]

I did like the powerband of my 150hp CV engine, torque was substantial and came on hard off idle. With stock intake/exhuast it was rated something like 280lb-ft at 2500 which is pretty respectable.

With the same shortblock, E7 heads and a HO cam it really comes alive 3k+... which is a RPM I rarely venture so overall it feels dogier during my normal driving.

Too stinkin much work to switch back, cam and heads are in storage in case something else takes me that deep in the engine in the future.

this is not a 300 dollar engine, smartass! so far there is easily over 5 grand into this motor so what is 700 more? ordered torque monsters 2 months ago and cant get any repsonse from them now.

 

[dangerranger83]

The engine unmodded is worth 300 with everything on it. I got mine for 100 and it didn't have much on it.

If you have put that much into an engine then why are you asking about what bolts on and what is worth it? Get a custom set made since it sounds like budget it's out the window.

And 5 grand into an engine and it has factory heads on it, not saying they haven't been ported, but I would have expected after market aluminum heads on it.

Next time a bit more detail on your setup would be nice. 5 grand into an engine means you're going to need at least torque monster headers if they fit.

Yo, smartass! Don't get pissy with us when you haven't told us a thing about your motor except that it had GT40P heads.

Since you won't take the time to tell us what you have I went and dug a little. Per one of your previous threads asking for what you need for your engine.

i have a 302(bored 0.20) roller motor (late 80's) completely rebuilt with comp cam, pistons etc... gt40p heads, edelbrock performer rpm intake, edelbrock 650cfm carb but i am not sure which water pump and pulleys to use.

Hate to break it to you, but you have a 2000 dollar motor there if you bought the best aftermarket off the shelf components you could. Yes the GT40p are about the best factory 302 head, but they are far from the best head. Even among factory heads once you start porting and polishing the GT40p gets left behind, it can't be taken as far. On a 5000 dollar motor the first thing to go would be the heads. You could have a nice stroker motor with aftermarket heads for that price.

For what you have get a set of cast Explorer manifolds, they will fit and be plenty for that motor. Save you money and when you eventually get a good set of heads (you will if you are any bit of a gear head) get a set of headers that work for them.

As for the torque monsters you may want to cancel your order. There's a few threads about it over on explorer forums about those, seems the guy has gotten a little flaky or gotten out of the business. I think that they have the info for the company that actually made them for that guy.

Before you get huffed up about my post you should know that I am doing a very similar build. 1986 Ranger getting 1998 Explorer 302 w/ GT40P heads. Biggest difference is that I am keeping the Explorer's EFI system. The motor is going in stock for now to make sure it is wired right and get the bugs worked out. Once I'm sure I have a successful swap I'll be building a 331 or 347 stroker to replace this motor. Rather than spending big bucks on a set of torque monster headers, I'll be using the cast logs for now. When that other motor is getting built I'll get a nice set of Tri-Y headers (won't work on 4x4) for about $200 and spend that other 500 towards a nice set of aftermarket heads. I'd rather spend 1700 bucks on better heads and headers, than spend 700 bucks on headers and wish that I had better heads.

not meant to be a smart ass statement in any light.


its the basics, most guys do a budget swap initially and wont pop for the headers...the guy thier reporting to have issues with, did a killer job on the tm headers and did farm the work out after it was finalized. but to bring costs down we need volume. most guys start with takeout engines, freshen em up a bit with gaskets and paint maybe and drop them in. you asked a specific question and got a answer. those headers are best fit for what you asked for specifically.. whatever reason you chose to limit yourself was your business.

a solid sbf 400 plus hp build that will go 200k in a work environment costs me 4-5 grand to do too. it sure as fawk would never have those retarded heads on it. those are low budget heads....(a great thing in itself) but simply put, if i have to pull them off cause the valves are seepin i cant justify the cost of freshening them up with real springs and buying new bolts or studs and gaskets to reinstall them. rather put Chinese alum heads on then have to fawk with the header issues.

which is why...today.... i would run the newest lowest mile ls i could afford first if starting from scratch.

plop a l/s takeout in with more then double the hp of a vic motor and better economy all around for nearly the same cost as a typical 302 windsor which the newest ones are 12 years old now.... ship your ecm/harness shit to 150 dollar tunes and 450 bux later you have a good tune and paint by number wiring job.

and no need for 700 dollar headers.


i understand frustration of not getting shit you ordered when you need it...

while sometimes, it takes time to get them headers...they are nice. well the ones i have seen were top notch.

...i figured you would try to find a used set first....eventually guys get real heads and sell them and run longtubes etc.

maybe i should have mentioned that first

And after reading up on the gt40p, gt40, E7 and my current E6 heads, if I had to choose another type I would go for the E7 or gt40. The gt40p can't even handle an HO cam lift, which is what I'm running.

But personally I will stick with my E6 heads, puts the torque at the lower RPMs were I want it. Plus I'm running the stock explorer headers. Worked perfectly for my swap and give the back pressure I need. But the downside, keeping the plug wires off them.

If I were you, get a different set of heads while you still can, makes life easier down the road. And if you got a deal on them, now you know why.

i think your not understanding all of the p issues.
they take lift....just a cost issue compared directly to e7 heads.

i run standard 40's just because its easier and cheaper.

problem is even with ho cam, gt 40 heads and intake/tune i had more torque anywhere over e6 heads...i was also close to 10 to 1 though.


its all in comparatives though. the numbers we are talking about are so small i feel dumb thinking about it.

This is one person experience I'm going off. We have the same engines and almost the same setup but he has the e7 heads.

I like having the torque down low, I'm a lazy shifter but also having a 3 speed trans (np435) I need the torque there too. Being my truck is driven in town most of the time, I don't see high rpm situations to much.

I do understand the differences between the P's and non P's enough to say if you can avoid the P's, do just that.

But if the chance for a set of decent e7's came across me for the right price, nothing says I would pass them up and my engine not see them, always like a nice HP boost when I can have the chance.

Bob who did the original TM headers was basically a one man operation, taken over now by the people who did his finish welding. Don't believe he ever made sets for that old of a truck. New owners are a lot more responsive and quicker service. Explorer Forum did have a group buy going on a couple months ago. Can't see with what you have listed that is anywhere close to what a $5k motor is around here. Saying a Comp Cam means nothing. The "P" heads are the cheap upgrade for a lot of Mustang guys but require a spring upgrade first of all. Most of the guys here will really try and help so lighten up and give them some slack.
