Headers for LS swap? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Stepper86 · 02-16-2014, 04:40 PM

I searched the forum and net to find out what headers people are using for their LS swaps. Maybe it´s just my lack of skill with search engines, but I have not been able to find that many options.
Seems like Thorley and Schoenfeld are popular,but are there any others worth looking at?
I would prefere to go with longheaders.
All so, what type of engine brackets have you guys used with longtubes? Didi you have to move the engine forward to get the headers to clear?

Any advice apriciated!

Dynatech 70-81 Camaro I believe with the right mounts

Had a look at your link, these fit really nice. Looks like there are plenty of space.
Can´t see it on the picture, do they come with o2 sensor fittings?

If you want real "long tube" headers that fit great....http://www.dynatechheaders.com/m_camaro_70_81.html

Do you have these? If so, could you take some measurements for me?

I refuse to spend $600+ on a set of LT headers unless I'm absolutely certain they'll fit.

Those are sexy! and fit great looking at your pictures.

Did you get the 1 7/8" ones? is that all they have? did you do the catback as well?

kevmac · 02-27-2014, 04:20 PM

Just put pacesetters on for trial fit this morning. 72c7662 and4572 trans dapt plates.

No that is the only down fall. you will need to weld a couple bungs in, but the bungs can be had for a couple bucks to it not a big deal. I am really happy with them.

68c10airstream · 02-16-2014, 11:42 PM

Hi stepper86, before i did headers i considered mount location for stock a/c and exhaust position and i chose the 2001 organ donor mounts. They obviously work with factory low mount a/c and because the mounts sit low they are never in the way of any exhaust style. I believe firebird/camaro LS1 (98-02) and trailblazer-envoy-rainer with 5.3/6.0 are a mount that looks like a hockey puck horizontally positioned down low. These mounts just require a little fab work with 1/4" plate to the crossmember and then you will have nothing in the way. Good luck, Brian F.

BR3W CITY · 02-17-2014, 02:59 AM

There is some fudge, depending on what exact setup you are running. The TBSS cast manifolds are the jack-of-all fits on swaps, since they have an ultra low profile and clearance. The same goes for the hooker cast-style manifolds, which just like the TBSS mani's has all its runners into one main pipe, instead of the individual tubes, which add to the width and drop of the exhaust.

For longtubes, the DT's are still extremely popular since they are offered in the larger diameter for those needing the extra ponies.

I did not think of TBSS cast manifolds, will have a look at it.
Thanks for the tip.

I used to TBSS longtube pacesetters, but I did have to dent the drivers side header a little.

Andy4639 · 02-17-2014, 06:44 AM

Here are the long tubes that I used. They fit with hardly any frame work on passenger side. There not cheap though. I used regular motor mounts with neopreme with a adapter plate.

**First c10** · 02-17-2014, 11:49 AM

This is my Driver side header. They are headers from eBay they were cheap so I thought I would try them fit pretty good i didn't have to trim anything. But they are short not long type. I will post picture of the passenger side also. I a, using early classics mounts and trans crossmember.

**First c10** · 02-17-2014, 11:50 AM

Passenger side

How much is a "little" ? Could the frame be trimmed a bit instead?

Looks ok, do you have a link to them? It´s not exactly what I was looking for but might be worth looking in to.

smoky02 · 02-18-2014, 12:47 AM

I had to dent one of the tubes in about an 1/8 of an inch, it was touching the frame. But that is also using ECE mounts all the way back.

BR3W CITY · 02-18-2014, 02:48 AM

For 600+ my money still goes to DT. Just because of the large tube, quality, guaranteed fit, and the fact that he was the first to do them for us.

It's not a guaranteed fit. I don't think they'll work in my setup.

I didn't see you were a 4x4, I suppose thats the point of putting a transfer case in the description lol.

They should fit the 72 without issue, but truthfully I don't know how the 4wd changes your clearances. BUT I'm curious, because Doug does list one for 4wd

Those are SBC headers. The biggest issue with my particular setup is how far back against the firewall and how low the engine is.
