Mickey Thompson Scavenger Headers ID

[BmStang]

Trying to identify a set of headers believed to be for a early gto. Guy was moving and these were hanging in his basement. 13A is stamped on flange. The guy said he had a 64 Gto and never had a chance to use them. They are in real nice shape. Any help in identifying will be appreciated.

Comparing yours w/ this Round Port set reported as 68-72 from this thread...
https://www.yenko.net/forum/showthread.php?p=1237317 , tube routing appears similar other than 2'nd from front Driver's Side and Pass' front, likely for AC/Alt/Smog pump clearances but Cool is how yours appear way longer total length.
So, possibly 64-67 or later if few accessories also longer length needs more investigating...maybe off-road pipes?:hmmm:
Best of luck confirming what you have, M/T Super Scavengers are Super C:headbang::headbang:L!

I thought some of you might enjoy seeing my original set of M/T Super Scavenger headers for my 1967 L78 Chevelle SS back in '67 or '68. I installed them myself with the help of a friend. As I recall they didn't rub at all anywhere and the sound was simply spectacular! I believe I had to loosen a motor mount is all to get some clearance during the install.

Not too loud either with stock mufflers, but with a solid lifters HP Big Block there was nothing sweeter sound-wise!

Johnwhat did they cost you back in 67? If they were still in the box Nos they would be 3,000-4,500 today.

Well, I was in high school, and I had to borrow money from my Dad to buy the car (and paid back every penny working at the local IGA and my uncle's Standard Oil Station), so they were likely not too much.....I'd guess $200 or so? Remember, my new '67 Chevelle SS cost $3,443 (delivered to the dealer), undercoating was a whopping $35, and my car's L78 engine option cost was a whopping $237 included in the above cost! LOL! So, the M/T's were cheap by today's standards.

Oh, what we'd all give for a time machine....I'm listening to the Four Tops on Pandora while typing this :)

No better sounding header ever, IMO.

[scuncio]

Those are great! Would look killer on my '67 GTO :) :) :)

Hard to put a value on them but judging by my own experience selling Chevelle and Mustang M/T headers, I'd say anywhere from $800-1200.

Although $179 may seem cheap, a fella'd be lucky bringing that much home a week in '68.

[Chevelle SS 396 L78]

I'm still researching headers for my '67 Chevelle L78 Engine Build. For the dyno, and to stay as close as possible to my old M/T SS Headers 50+ years ago, I have been comparing the primary tubing layout of the Hooker Competition Headers with the photo of my orange M/T Headers (above) before I installed them. They are amazingly similar, especially on the driver side. Oh, the M/T's were so simple (thanks to the long collector with staggered lengths of primaries entering the large collector). If only someone still made accurate Super Scavenger Headers today!


Any thoughts on the Hooker 2455HKR Competition Headers? 2" primaries with 3.5" Collector dia. (just like on the M/T Headers). They are relatively inexpensive at $263.95 from Summit. I prefer the painted version, as I have an outstanding high temp header paint in satin black that I want to use. I'm just concerned about fitment. My M/T's fit like a glove (even back way before cadd design)! You'd think header manufacturers would have it together by now, thus avoiding install issues. Any input appreciated. Thanks guys!

I have bought two sets of the Mickey Thompson Scavengers now being offered by Nathan Schmidt at Sweet Ave Fabrication in Bismarck, North Dakota. He has also sold many sets to other guys here on Yenko in the past 2/3 years.

He bought the original M/T Dies from Bruce in Indiana and has been hand making the tubes and flanges to join into the collectors ever since. Amazing craftsman, great fitting headers and a sound like no other. He also ceramic coats them which is just so cool as they change colors to tomato red when they get hot, and back to bright orange when they cool down.

Call him up and tell him Graeme says hello. His shop phone is +1 701-471-3350 and he has a Facebook Page as well. https://www.facebook.com/Sweet-Ave-Fabrication-119946468092467/

Thanks! I will give him a call. I believe I may have corresponded with him a while back thru eBay when he had the SS M/T Collectors on eBay. He didn’t make the entire headers at that time as I recall. So he was able to get the dies from the guy in Indiana? That’s great! Nice pic btw! I painted mine VHT White back in the day. I never had any issues with those headers and they tucked up nicely when installed...they were not too low!

There really isn’t anything like the sound when Super Scavengers are installed, especially with solid lifters! 😉

Isn't that the truth. Here's my old Nova with a little stroker breathing through a set of orange pipes from Nathan.

And here's my most recent build. A cool 69 Z/28 with another set of these orange headers from Nate.

Wowza I had no idea someone reproduced them. I’ll be calling him also. Thanks Rob

[NorCam]

Here's the first set he made for me. They were mocked up on a dummy block that was set into a Camaro subframe before being hand built and beautifully welded. I ended up using them in the Nova and they fit with perfect clearance as well. Nathan is a wickedly talented fabricator who totally gets it. And he can have them ceramic coated in any color from what I was told. Most people now go with a flat orange. The ones shown below were a semi gloss. I had him add exhaust bungs to each set so I could tune the car using an exhaust gas analyzer to read the A/F ratio.

Here's a pair that I own. I believe they are 1955-1957 Chevrolet.

[chevyandpontiac]

correct those are tri 5

[markjohnson]

There are some great YouTube sound clips for anyone unfortunate enough to have never heard a set of these. It’s a very unique and very cool sound!

[Chevelle SS 396 L78]

I'm thinking I may just buy a set of the Hooker Comps (2" Primaries, 3.5" Collector like the M/T's) JUST for my engine build & dyno runs. They are cheap.

I can then have a set of Super Scavengers made for the engine when I put my new engine build into a 1967 Chevelle SS (which I am still searching for).

I don't think I need the M/T's for the dyno, although that would be pretty cool! :headbang:

I'd be interested in knowing what your engine dyno'd with those M/T's however?

I always believed my '67 Chevelle L78 was in the 450HP range with my M/T Headers back in the day...based on my butt dyno! I don't think I was much off, and likely too low based on what I've learned since.
