Any guesses as to what brand headers these are? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hulk Will Smash · 09-30-2010, 12:34 AM

Pretty thick tubing and flange. 1-3/4" primaries and 3" (OD) collectors.

They came with my truck and are a bit grungy but seem like they're in decent shape. Just don't know where they came from.

Thanks!

hmmm from the look of it. they look like big block chevy headers..

haha

but i have no idea

Hulk Will Smash · 09-30-2010, 01:08 AM

Guessing that they're Doug's or Patriots? But I don't really know...

from the little bit of poking around i did a little bit ago looking for headers the only ones i found (but i didnt look that hard) that had the air injection tubes on them where the doug thorleys but i could be wrong if u wanna sell them though let me knwo id be interested in them

Call me crazy but they look like home made smog headers made with brake line fittings and brake line.

Hulk Will Smash · 09-30-2010, 01:15 AM

Just trying to figure out what they are for now. Don't want to get anyone in trouble with the classified police...

I would definately say big block chevy headers, whether they are from a truck or fit it not sure, plus the are smog headers, and probably pre 87 since there's no o2 sensor bung.

check the collector, sometime there are numbers there that is a factory part number and will let you trace them back.

Hulk Will Smash · 09-30-2010, 12:21 PM

Yah, I guess I should bust out the wire brush, get the dirt off and see if I can find part numbers. Good point about the O2 sensor bung.

I doubt they are Thorley's. Thorley Headers have the tri-y thing going on. These are straight primaries all the way to the collector.

You bring up something I've been wondering about lately but have been too lazy to look into... Are Doug's Headers and Doug Thorley the same company? I think I remember someone telling me that Thorley sold out and then went back in business (or his brother did?) Under a slightly different name. But that's an old memory, so anyone know?

Yes.

Looks like they are headman BBC smog legal headers. I'd almost bet money on it.

Hulk Will Smash · 10-01-2010, 01:09 PM

Which Hedmans? The one's I've seen on Summit for the BBC trucks (other than Doug's and Patriot) all have #5/#6 primaries that go straight down to the collector rather than up and over #7/#8. On the website, Hedman only lists one style (no photos) and those have 2" collectors and ball flange.

They're laid out exactly like these Doug's (but no stove pipe) http://www.summitracing.com/parts/DOU-D3342/?rtype=10

And also like these Patriot

http://www.summitracing.com/parts/PTE-H8054-1/?rtype=10

But don't look anything like these:

http://www.summitracing.com/parts/HED-69117/?rtype=10

Like I said, mostly just curious. Thanks!

And to add to the confusion, I think Doug's Headers is owned by Petronix (who also owns Patriot which would make sense looking at the pictures) and Doug Thorley Headers is owned by someone else (interweb says either ex wife, Jardine, Summit or a private equity consortium owned indirectly by Bigfoot, Elvis and the Lock Ness Monster).
