Long Tube Headers for '73-'87 LSX Swap - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

C15_Sierra · 11-27-2011, 10:44 PM

Just installed the '88-'98 Schoenfeld LS Swap headers on my '80 GMC. Fit with plenty of frame clearance. I had to remove the A/C evaporator box to get the passenger side in. And its a tight fit with the drivers side control arm, but it clears.

Looks good

What adapter plates did you use? Do they hang below the frame rails?

They don't hang below the frame where the collector exits, but they are visible where the frame rails rise to the suspension pickup points.

A couple points of concern for later, as I haven't run an exhaust yet: the passenger side collector exits in line with, and not too far from the trans crossmember. I'll report back when I get the truck started and visit the exhaust shop. Also, I'm running a B&M shift cable, and the exhaust runs VERY close to the cable, so I'm going to have to put in a heat shield

I'm running Swaptech adapter plates, engine mounted 1" rearward

The mounts are the original on frame. An the ones on motor are summits think was $74 can't find receipt for pn #. The linkage on trans or by headers. I can take a pic later after stops raining.

Shenk10 I am not sure on that

Well looks like I will see if the eBay/chinese stainless F-Body long tubes will work with a 4x4. I already bought them and should have time tomorrow to test fit them.

Updates to follow...

I tryed speed daddys and they hit everything. Trans, shackles, shifter linkages, frame. If you spend time to modify them a lot they may fit. Driver side fit like a glove other then exiting on the shackle untell i tryed to shift from park to any other gear. Hope yours fit better.

Speed Daddy's?

y5mgisi · 12-08-2011, 11:20 PM

Street and Performance also makes a set designed to fit 73-87 4x4 and they have a really cool 4 bolt collector. They are also pretty pricy. Dude on CK5 ordered a set so we should have a review soon on those.

harnalien · 12-08-2011, 11:29 PM

I have the Schoenfeld's and they work, but I did have to get a Lokar shift linkage because the factory setup hits the O2 sensor.

Ford Assassin · 12-09-2011, 01:26 AM

I think I am going the start a new LSx long tube header thread just for the '73-'87 ('91) 4x4 guys since I don't care which headers fit 2wd and I doubt many other 4x4 owners to either since about the only thing 4wd and 2wd share is frame width in terms of long tube headers.

y5mgisi · 12-09-2011, 03:30 AM

Not long tubes but maybe it would help somebody. S&P headers for these trucks with these motors,

Not meaning to be rude dude, but no one cares about shorty headers in a thread TITLED: " Long Tube Headers for '73-'87 LSX Swap".

Besides, I am sure there are MANY header companies that make a shorty header that fit WITHOUT paying S&P's a**rape prices.

Shon · 12-09-2011, 09:42 AM

Heard DT was revised their 323s to work on these trucks.....should be ready mid Jan....

shenk10 · 12-09-2011, 01:22 PM

has anyone ever tried the schoenfeld headers on a 4x4. I know they only say 2wd on their website, but on their website they aren't even for our years. I just ordered a set and haven't put them on yet. I wish there was some way for me to test them to see if they would fit on a 4x4.

flamingbig10 · 12-11-2011, 01:06 PM

I'm using 64-72 elcamino hooker ls swap headers

shenk10 · 12-27-2011, 10:21 PM

Well I bought the Schoenfeld headers, and they seem pretty nice for $250, although they are not painted or coated. They come close on the driver's side lower control arm and frame rail but not a bad fit at all. Passenger side is clear except I have a sonnax servo that sticks out a lot more than stock that comes close to hitting.

gringoloco · 03-31-2012, 10:08 AM

To those with the Schoenfelds, how do the plug wires fit?

C15_Sierra · 03-31-2012, 05:13 PM

I used Jegs wires, they fit for me

dkauffman05 · 05-25-2013, 11:19 AM

Anyone ever find a 4x4 header ?
Posted via Mobile Device

Ford Assassin · 05-25-2013, 11:48 AM

I know of a custom set of long tubes that will work, they are stainless. $500 + shipping.

Maybe if we get a group buy I can get them for alittle less.

Anyone else interested in a group buy?

I've been talking to a flowmaster rep here in so cal. He told me if I had a couple dozen people show interest they would use my truck as a test fit vehicle and build a set. If you guys are still looking for these I might be able to talk him into this. Please let me know.

Add me to the list! Although I'm a few days from making a big purchase from Summit for a new fuel cell headers, motor mounts and miscellaneous parts. Can't wait to get this truck on the road!
Here's the headers I plan on running.
