Has anyone found a set of long tubes that fit our trucks with LS engines? I've read all over the internet that this and that are close of don't fit at all but never a definite yes. If I cant find anything I'm going to use BBC headers and LS flanges buy it'd be nice to just buy a set that will fit

both jegs and summit offer conversion headers from several different companies both long tube and shorties. they are suppossedly made specifically for ls swaps into c10s. do none of these work?

just an example. there are many more. this swap has become pretty common. i know of 5 squarebody ls trucks just in my immediate area. point is, more companies are coming out with conversion parts for this swap every week seems like.

I have a set of these, #45690, but Im still gathering parts for my swap and have not started yet. So no review of their fit yet. They at least LOOK good. :)

Elcamino LS headers fit look at FlaminC10's thread.

has anyone tried the Gibson GP139s ?..made specifically for c10 trucks with LS swaps , no modifications?.. I plan on ordering a set soon....$500 for Ceramic coating isn't bad compared to Doug T's or Schofield, or Pacesetters that might fit with persuasion... any thoughts?
-
Never heard of them. got a link or PN?

I know nothing about those but I would call and ask if they were designed on a 67-72 and they should fit a 73-87, or if they were designed on a 73-87 and they fit 67-87. The latter is true, the former is not in most cases as the firewall placement is drastically different. I would also ask who's engine mounts are required and if the engine is mounted in the same spot as a SBC. A lot if 67-72 specific mounts put the motor about 6" forward. Tried these out a long time ago.

ok, didn't go with the Gibson's...money factor...went with schoenfeld 1302ls1.. and they fit like a glove...I have 84 c10--- I know they say 88-98 but the fit the 84...only issue I have is I have to move my o2 sensor because the gear shift linkage is hitting the 02 sensor...just going to move the bung hole...no biggie...
-
I also went with the Hedman Muscle Rod headers, but they only guarantee fit with their mounts.
-
I used Pacesetter Trail Blazer SS headers. I only trimmed the frame very slightly to keep from scratching the finish on install. The ONLY issue I had was the placement of the drivers side O2 sensor. It pointed right at the gear selector. Other than that, they fit very well and tuck under the frame.
-
I got ebay speed daddy F body long tubess and they didn't fit worth a crap. Definitely avoid them. Both sides are in the shackles, the driver side collector is pointing right in the frame rail. I have an NV4500 with the slave on the pass side, under the starter, I had the flatten the side if the primary to get it out of that. I got them on and they were only like $160, but I've had them on and off probably 30 times, I've cut and welded and heat and beat and they are still real tight. So there's my review, don't be cheap. I was

I see that this is an old post, but it has plenty of views to merit a response in hopes of helping future swappers.
I had researched this topic earlier this year when I wanted to find affordable headers that would drop right in for my 5.3 swap. During my search I came across a company named Speed Engineering. http://www.speed-engineering.com/ (http://www.speed-engineering.com/) They sell a bunch of LSX conversion products, specifically they sell long tube headers for the C10 LS swap. I purchased their headers and couldn't have been happier. They dropped right in without any interference or modification.
Polished 304 Stainless with 3" collectors. You can buy them with either 1-3/4" or 1-7/8" primaries. Under $300.
I was very impressed with the bend quality, weld quality, and fit of these headers. Check them out.

Hey Tim, thank you for this post. I'm planning my swap now into a 86 gmc c10. I'm going to buy these headers after reading what you said everything else I've researched had some figment issues.
What did you use for motor mounts? I have a th400. Did you buy a modded harness? Thanks in advance.

The Speed Engineering headers for C10 LS Swaps fit very well. Automatic transmission trucks only. They do say you need the MSD wires because the headers are tucked so close to the heads. Also, one thing to note with many of the long tube headers is that the collectors aim directly at the stock trans cross member. Because of this I purchased the scorpion fabrication trans cross member available on this website. I could have routed my exhaust down and around, but it wouldn't have looked good.

The motor mounts I used are from ICT Billet. SBC to LS Engine Swap Bracket Set. I bought them on Amazon.
http://www.ictbillet.com/
These mounts adapt the stock 305/350 motor mounts. My trans is a TH350, but that shouldn't matter for the motor mounts.
I will post pictures once I create my build thread, but the ICT Billet website has some pretty clear pictures for reference.

Thanks again. I don't want to replace crossmember, so I guess I am still searching. Thx for the advice.

With the speed engineering headers you have a good 6-10"" before your exhaust would need to bend to clear out of the way. The reason I did not do that is because I didn't want to make a tight bend directly after the O2 sensor. The other reason is that my current exhaust setup is temporary and I installed it with clamps along with straight section of pipes. The Scorpion cross member is double-humped so the pipes can go straight back. The stock trans cross member is bolted on so removal is easy. The Scorpion Fabrication cross member also uses bolts to attach. All you need to do is drill a few holes in the frame and bolt it on.
The picture below shows my setup (I just went in my garage and snapped the picture now). On the left you can see the collector on the headers. Attached to the collector is a 3" to 2.5" reducer. You can see the tubular transmission cross member (Scorpion) above the pipes. The trans mount bolts are in the same location as the stock cross member for the TH350. As mentioned you would have 6-10" at the end of the collector before the stock cross member if. I hope this helps.

I just went back through my phone. Here is a picture of the passenger side Speed Engineering headers mocked up on the engine.

Here are the headers I used on my 87, they fit very well and are relatively cheep for what they are. C10 LS Truck Longtube Headers 1 3/4" (Conversion Swap) LS1, LS2, LS3, LS6 they are on eBay for 249.00.

What long-tube headers are available for LS swap on a 4WD square-body? I know the Schoenfeld ones, but I really don't want slip-fit collectors! I don't want to take my entire exhaust loose to slide back the connections. I would rather have traditional 3-bolt collectors, and I certainly do not want any aftermarket ball and socket collectors!
I have seen those Gibson ones, but don't know if C-10 headers will fit a 1991 V3500 and the Gibson ones are way too expensive!
Before the swap I had Doug Thorley headers in it with the 454.

Try speed-engineering.com. They offer polished stainless long tube headers. I bought the 1.875" 2010 camaro headers for my 86 k20. They fit nicely except you'll have to route the passenger side around the transmission cross member or move the cross member. I'll post pics when i get them finished.
