Thorley Headers???

[69Rathead]

It may have been on the old forum but it seems as if someone once posted something about Thorley headers and that they fit really well...can't remember if they were long/short or what engine application they were referrring too does anyone remember who posted or what application it applied to? Thanks for any info!

Most Thorty's are of the Tri-Y design( 4 into 2 into 1). This makes fitting all the tubes easier(usually). http://www.thorleyheaders.com/

My dad had put a set of doug thorley headers on a 66 chevy pickup, they were a try y design and fit and finish was awesome, well worth the money in my opinion.

[69Rathead]

Cool thanks for the input...but it seems like it was someone who had a '69 Camaro who commented on them. I like the Tri-y config that is one reason why I was looking at them. I'm taking my time to find the right combo of cost/performance/fit...I'm on a limited budget!

you may want to check them out. I have a set and they are fantastic.

[Rick Dorion]

What heads are you putting them on? I want to use them for my Pro Toplines 180's and am discussing with them their port size.

[protour_chevelle]

My dads got a set for 56-64 Impala's(and that type) fender well headers. They look super cool! Quality header from what I can see.

Can't help much on where the post is though.

I have them on a 70 nova which is basically the same, and they fit nicely. It gets a little tight around power steering pump, but everything cleared with no modifications. I was very happy with them as well.

[69Rathead]

I know what you mean about the power steering pump! I have old (I think Flowtech cheapies) headers on mine that barely clear also (<1/4"). I'm going to need to replace them soon as they have been on the car for 20+ years or so and I can tell they will be springing a leak soon. They are very oxidized and quite thin. I just want to replace them with a better quality Header but not one that will break the bank...seems like the Thorley's fit the bill somewhat. Thanks for the input!

I have a set of Thorley headers on my car and its been daily driver for past 1.5 years and still is chromed color, didnt discolor much at all

[69Rathead]

Thanks for the input! I'm pretty sure I'm going with Thorley's. Seem to be pretty hard to beat at price per quality and performance and I'm trying to get this car completed on a low budget.

Sorry I'm late to the party. Most likely that was me posting about them on the old board. Here is a pic and link to more pics. So far I love them.



More pics of headers

The ground clearance was my favorite part! On my nova, you can't even visually tell that I have an aftermarket exhuast from the side. Of course, there's no doubt once it starts...it's LOUD. Flowmaster's fault, though, not thorley's.

[69Rathead]

Hey it's never too late! Thanks for sending link to the pics too! A picture's worth a 1000 words as they say. I am definitely going with Thorley! Lots of clearance, Great price, and good performance. Ground clearance is unbelievable compared to mine...they are sweet!

Headers were manufactued by a company called "Doug Thorley" headers at one time. Now there are two distinct companies, Doug's headers and Thorley headers. I hear this was done for a variety of legal issues but my understanding of the bottom line is that Doug's headers reflect newer development while the Thorley headers tend to be reproduced versions of headers made in the "Doug Thorley" days. I have heard the Doug's headers are of higher quality. No slam intended to Thorley as I have heard good things about them as well.

[69Rathead]

Thanks for the input. The main reasons I am going with Thorley's over dougs is Price and Fitment. None of Dougs (www.dougsheaders.com) show a fitment with stock AC (which I have) and one set calls for a different Power steering pump mod or bracket to clear. They are also not Tri-Y (helps with clearance issues) Also they are over $200 more than the price of the Thorley's at Summit that will fit my AC car with no mods etc. I am sure however you get what you pay for and I can tell Doug's are better quality. For my application the Thorley's will fit well, perform better than the old (almost rotted out) cheapie circa 1975 Flotech's I have now, they are above average quality, and I'll save over $200 to boot! :icon996:

does thorley make a 1 3/4 primary header? (or dougs)

[69Rathead]

Jay I tried looking some to find out but from what I can see Doug's does make them but Thorley is kind of unclear. If I were you I would just call them and ask to make sure. Good luck

I'm kinda late too, but was wondering if you can verify the part number on these headers. Are these Thorley 376C?

I've got a 68 Camaro with a new 383 and factory power steering. I kept the original 327 frame stands, but was told this may cause fitment problems with some headers. Looks like there's lots of room in your photo. What frame stands are you using?
