Speed Engineering LS Swap Headers Findings
5 Attachment(s)
I've been looking through the site to see if anyone had really used these headers in a swap, and I only came across a few threads where folks asked about them, but never seemed to actually try them out. I was looking for a set of budget headers for my little brothers C10 and decided to go ahead and take the plunge and order them. Although we are still mocking things up, on the initial test fit these headers seem to fit very well. There is lots of clearance from the frame on both sides, and they only slightly hang below the frame giving great ground clearance.
The quality of these headers is a lot better than I expected for being less than $300 shipped, they have thick flanges, are 304 stainless steel, and 02 sensor bungs are already welded in. These are the Speed Engineering 1 3/4 in. longtube swap headers. I apologize in advance if pictures are crooked. If anyone needs any specific pictures, or has any questions let me know. Hopefully this will help a few folks out. -Zak |

Hi 67,
I see they list two 1 3/4" headers, one for camaro's and one for 1999+ suv and trucks, which ones did you get? I was also looking at PB but htey are 350 before shipping. Looks like Speed Engineering also has shorties for 169 for C-10, that might be an option for me as well. |

Houston Ben,
These are the c10 ls swap specific headers. Here's a link to them on their website, they also have the longtubes in 1 7/8". http://www.speed-engineering.com/ls-...2-ls3-ls6.html -Zak |
Re: Speed Engineering LS Swap Headers Findings
I put the shorty set on my 87 burb and fitment and quality are great for the price.

nobox351y,
How long have you had them on? How have they held up? That was one thing I was curious about since I'm still a ways away from starting the truck. -Zak |
Re: Speed Engineering LS Swap Headers Findings
I have a couple hours of run time on them. I am still working the kinks out of my setup. I am expecting them to last. Flanges are thicker than pricey headers Ive purchased, weld quality is good, stainless is awesome.

Re: Speed Engineering LS Swap Headers Findings
Those look nice! How's plug wire routing?
|
Re: Speed Engineering LS Swap Headers Findings
On the shorty version fitment is good, a couple of stock plug wire boots touch the headers. Especially number 5.
Got 200 miles on my set and no leaks, and they sure look nice. |

Sik66,
I have the ones in the first picture. -Zak |
Re: Speed Engineering LS Swap Headers Findings
I ordered a set of the shorties for my 77 C10-6.0/4L80E swap. Had to trim the lower ears off the trans. Other than that, I am very pleased with them.

Re: Speed Engineering LS Swap Headers Findings
nice.

Re: Speed Engineering LS Swap Headers Findings
Has anyone tried these on a 4x4 yet? I'm getting ready to start an LS swap on my 84 K5 and am trying to figure out the exhaust...

Re: Speed Engineering LS Swap Headers Findings
I'd be interested in hearing if anyone has used them in a 63-66.

Re: Speed Engineering LS Swap Headers Findings
I've got them half installed in a 66 right now. I have a 4L80e so the PASS side does not fit and you have to trim the dust cover ears

Re: Speed Engineering LS Swap Headers Findings
have you guys these for sale that are not chrome or shiny?
|
Re: Speed Engineering LS Swap Headers Findings
Speed tech crafts them polished. After a few heat cycles, they'll turn a nice, hazy bronze.
|
Re: Speed Engineering LS Swap Headers Findings
They post right on their website to use MSD plug wires. What is the best stainless header bolt to keep them tight?
|
Re: Speed Engineering LS Swap Headers Findings
Speed Engineering has a lot of happy customers. They are a sponsor and have a long thread on LS1tech.com about their f-body headers. You can't beat them for the price. I am not surprised to hear that these swap headers are good units as well.

Re: Speed Engineering LS Swap Headers Findings
Any pic. of the pass. side and how low below the frame do they hang?

Re: Speed Engineering LS Swap Headers Findings
I am doing a LS3 / 4L80 in a 1965 c10

Re: Speed Engineering LS Swap Headers Findings
These things look awesome.. My bank account would appreciate it if I would stay off this forum! LOL HAHA

Re: Speed Engineering LS Swap Headers Findings
bill1969camaro,
It's kind of a bad camera angle, but in the fourth picture I posted you can kind of get an idea of how low they hang. It's been a while since I've looked at it, but I don't believe it hangs down much more than 1/2-3/4" below the frame, if that. Of course I have the 1 3/4 headers, the 1 7/8 may be a bit more. -Zak |
Re: Speed Engineering LS Swap Headers Findings
I bought the shorties - http://www.speed-engineering.com/fea...c10-truck.html .
So nobody runs into the same thing I did, stock plug wires will NOT fit, 3 of them on the driver side are pressed up against the headers. I was going to order the Accell 9000 series ceramic 135degree wires but some reports indicate they are not long enough and pull off the coils. So I ordered the Taylor TAY-76046 from Summit. Will see at end of week if they fit. :metal: the notes for the long tubes indicate they are tight but vendor doesn't have the same warning for the shorties. |
Re: Speed Engineering LS Swap Headers Findings
I have them on my 63 with a t56 and ECE mounts. They fit great. Nice quality for the price.

Re: Speed Engineering LS Swap Headers Findings
I instaled the 5.3 in my 65 over the weekend and put the 1 7/8 long tube headers on today, they fit fine. I'm not sure if the following will be of any help to anyone but I'll add it anyway. I used the original V8 stands in the rear position with ICT Billet mounts from eBay. The mounts are in the second position from the rear of the adapters. This allowed my trans mount to match my crossmember location because I didn't want to mess with the driveshaft length. I had the driveshaft shortened in 2001 when I changed to a 700R4. The only problem this has created that I've found so far is the rear coil on the passenger side hits the firewall, not the end of the world. The drivers side has a ton of room but the primary for cylinder #4 is about 1/4" from the frame. The ground clearance is higher than when I had long tubes on the ZZ4 I pulled to the 5.3.
