'67 project nightmare ls1 swap

[Jamie @ Doug Thorley]

Hello everyone. Let me start by introducing myself. I'm the design engineer at Doug Thorley headers. I have always been a big fan of the '67-'72 era chevy trucks and have the pleasure of working on truckin' magazines "67 nightmare". Some of you may already know about the project but I will give the rest of you the skinny...

It's a 67 c-10 1/2 ton
It's currently undergoing a frame off resto and has entirely new suspension.
It's a ls1 motor swap
disc brakes all around.
A very nice truck is coming together here

Why I'm here...

First, let me say that this is not a sales pitch. I just want to let you guys know how we are involved with this truck and our future involvement in our community here.

My intention is to build a specific header for this swap in particular. The first of it's kind as far as I know. It's a tri-y design and is designed to work with the classic performance products swap kit. The headers are still under development as we speak and I WOULD LOVE TO HAVE YOUR INPUT.

so, having said all that, please feel free to hit me with all the questions you may have about the truck or exhaust products as I'm here to help.

Thanks for the welcome.

I'm not opposed to giving forum discounts but first I need to take care of Josh and contribute a little more to this site other than info ...

These are built so that the very bottom of the collector flange is around an inch above the frame so they will never hit. This is the only shot I have of where the collector terminates but you get the idea....

Thanks for the warm reception everyone!

Welcome to this amazing forum. I'm sure you will get all the help you could ask for. I know I did, and still am. Looks like an awesome project. I wish I could get some funds for that together for my truck.

Dude, Welcome to the board from TRUCK BUILDER magazine, the other guys. Those headers look awesome!!!!!

Just a little input, how low are they gonna hang.It always looks funny to see a '67-'72 sitting still and notice the headers hanging almost all the way to the ground. Sorry to be the buzz kill here. Just an editorial tech question?

No problem Josh. The headers are designed well above the bottom of the frame rail so there really isn't any chance of the headers draging no matter how low the truck sits. Once the headers are done I will post pics of the bottom side for you guys.

Maybe we can do something together? I'll pm ya...

Welcome..

If you look around on the build threads in the truck year boards you will find people putting just about every imaginable GM powerplant into all years of trucks. LSx swaps are very popular for those with the cash to do them and there is a dedicated (obessive?) sub community that is convinced that the best powerplant of all time for a GM truck is a Cadilac mill.

I'm betting that you will find a wide range of product opportunities here.

*****in!
bout time somebody got off their arse and made some c10/ls1 headers.
Wonder how the fitment would be on an 86, should be pretty close.


ps, is that a typhoon intake? Hard to see..

Thanks, figured it would be nice to just purchase a set rather than make something else work.

I might be able to make an educated guess if I had good pics of the engine bay of an '86.

Yup, that's the typhoon intake/throttle body. Pretty nice piece too.

I plagarized that one from one of our board members (BLAZAIR???) that does some FANTASTIC renderings. I still haven't decided what I'm going to do with the Crewcab yet. My original intentions was a very mild build........

I used the ECE motor mount setup in my 2 builds. Any idea if your headers will work with them? If you want to send me a set, I'll test fit them for you, . Supposedly Sanderson was working on a set, but it's been almost 2 years.......

That is a possiblity on the test fit.

The builder of this truck used Classic performance products p/n 6372mp-t perch kit, cpls1-k plate adapter kit and the cp9427 crosmember kit. The motor mounts to be used are 59-70 passenger car mounts (chevy). He went with the 4L60 trans with the gear vendor unit. When we are close to completing the first product run, I will be in touch with you Rob.

Here is a couple of pics of the perches...
