Spdrcer34 is going V8!....

[Spdrcer34]

Matt...go ahead and sell it....

I have a line on a 2WD transmission...

Thanks anyway..

Okay...I test fit the 88400's on the Motor, and ran into a SLIGHT problem on drivers side head...






When bolted on, the 2 forward spark plugs hit the primary tubes.

Are there any short plugs that fit in there? Or will have to modify the primaries?

Those headers look great for the Explorer, they may possibly be close in the later trucks.
Those are GT40P heads so the plugs come out straighter. There are shorter plugs, I have read of people looking for them. Try searching on the Corral forum, all I know is that what are available are very expensive. If they will work, just use the ones that you need.

FFFFFFFFudge.

I found this thread on the SBFtech forum;
http://sbftech.com/index.php/topic,15178.0.html

That leads to the Accel P526S plug, which runs about $15 it seems. There is no picture on the Accel site below, but maybe another plug is out there as well.

my quik search also led me to the p526s.

Summit has them for 16$ apiece. Amazon has them on sale for under 5$

 

[CDW6212R]

That's good, and it would be wise to see what kind of length difference there is first. You need quite a bit of change to fit a plug boot in there. I really doubt that anything will work with those touching as they are. I'd be tempted to choose between a header modification, and a device used between a shorty plug and a normal plug wire. Meaning almost any plug wire is going to be right on the pipe, and die after a short life. See what you come up with for a plug and clearance.

 

[Spdrcer34]

Maybe I can find a Drivers Side header that fits better...

Matt, I think I've asked this already, but do you have GT40P heads?

Ryan

 

[seth247]

Yeah I've been wishing I didn't for a while now.

They're a pain in the ass.

man thats rough

I fear many have been down this road ahead of you and they end up with either:
1. torque monsters
2. expensive custom made
3. hack job hand made
4. FMS headers
5. stock manifolds

obviously you can chop that header up a bit and re route those two primaries, just be aware of the fitment in the truck also

I would be running stock manifolds if Robert never called me and said hey guess what! LOL now I have TM headers on all my 5.0L's and likely always will

We were never happy with teh conversion headers on the market, the Advance adapters long tube units wont even fit past an AOD bellhousing, especially on a 4x4, I dont even think they would on a 2wd, I guess for those you must use a C4 auto? I dunno, bad design IMO

the shorty headers from Advance Adapters also did not get great reviews for fitment and finish, the TM headers come in with top ratings in all departments.... so they are $$$$$$$$$

I look at your pics and try to come up with some wort of semi simple solution.... double flange thickness? nope
dent a tube? nope

looks like its re-route (cut chop rebuild) or trash that header

 

[WickedWindsor]

If this was me in this predicament, I would be looking for some E7TE's, GT40's or off-the-shelf small block heads.
Your header options will be far greater for your application here.
Support for traditional small block heads goes back to the 60's whereas GT40P had a run of, what, 3 years? I know they flow slightly better than stock heads, but it is really worth all the fuss?

Don't give up on those headers! They look great.

 

[seth247]

Ryan,

Are the headers bolted all the way down in those pics? And the plugs are just barely touching? Or what?

Thanks.

 

[Spdrcer34]

Bolted down as much as I could get them. the 2 plugs were touching the primary when I started to snug it down.

I would say they are about as close as they would be with a good gasket installed.

Ryan

 

[CDW6212R]

That may be too tight. I don't know how much shorter of a plug is available. How much trouble would it be to see if those headers are going to be good in the truck? If the headers would fit the truck really well, I might strongly consider normal heads. I would ask Jamie, how his headers have fit, not the TM headers. For the money, those headers would work very well compared to other choices. Those look a whole lot like the headers I used in my 86 Crown Vic. They were mid length headers, shaped much like those, but with collectors farther back.

 

[seth247]

I bought one of the short accels and it's being overnighted.

I will compare it to the stock plugs and see how much room there is to work. If it's short enough. Then 90 degree plug boots could do the job.

I hate to sound stupid, but what options are there for spaceing out the header? Double gaskets?

some 1/4 inch steel used as a spacer?

 

[Spdrcer34]

Matt...It's been done before.

The easiest way to do it, is using 2 gaskets per side.

The assembly will be something like this:

Head > Gasket > Spacer > Gasket > Header

There are other issues when attempting that though. You may actually run into the steering shaft at that point.

it really does not look that hard to cut that tube in a couple of spots, and have or make a new section to go around the plugs..... (change the angle and length just a bit)


I cant wait to see this Accell mini plug if it works HI FIVE!!

 

[seth247]

Freakin amazon is slow and there saying it wont be here till Monday but well see.

Those headers are tight enough to the block that I don't thing steering will be a problem. But is it possible for you to test fit them in your truck?

I'd like to know the headers will actually work before I start messing with them.

 

[seth247]

Hey Ryan can you take apic of your spark plug next to a ruler. at least get me a measurement?

Cause the plugs I have may already be shorter than yours, I don't know.

Thanks in advance.

Ditto Jamie, I noticed that the header is very tight against the engine, it comes out at a sharp angle. I think that there is plenty of room at the front there for the pipes, but that should be a last resort too.
