Anybody Remember the Mickey Thompson Super Scavenger Headers!
Now I,m reasonably sure the main idea was more towards ease of manufacture and low cost, than any effort at making a true race header and the squared off , overly long collectors were not well received , by the public if my memories are good.
the basic idea was that each primary tube could be cut to the same length ,but not necessarily end at the same point in the collector, this allowed you to use the slightly rectangular tube that functioned as a collector to enclose the ends and even if each header primary tube ended at a different point in the collector it still made welding the header fairly easy.
now the strange thing is that these headers actually DID run rather well and in fact allowed the engines to produce good hp, I remember my 1965 LEMANS that Id installed a 496 BIG BLOCK CHEVY engine in ran rather well with those headers.

I came across a very old set that had obviously been sitting neglected for decades in the back of a garage,I purchased them at a local yard sale,
(this is a picture I found on the internet of similar headers)
I picked those yard sale headers up for $10 just to clean up and hang on the shop wall as a decoration after I bead blast and repaint them of course

I never have seen headers like those Grumpy.
Super rare today.
I would hang onto the Mickey Thompson Super Scavenger Headers too.
If you ever sell, might bring several hundred $ on ebay.

they were semi-popular in some circles in about 1965-73 if I remember correctly.
Im not 100% sure of the dates but I remember having used them on my 1967 firebird, 1965 GTO (the GTO used chevelle BBC headers) and a couple other cars at the time.
we found they were both cheaper and more effective than the headman headers at the time, and for some reason they seemed to produce a wider torque curve which was noticeably more effective, in the mid and upper rpm range allowing my 1967 fire bird and my 1965 lemans with a high compression big block chevy 496 to run better than most of my friends cars did. plus they sounded really nice.

This style header is quite popular in Buick circles. So popular in fact that one of the national clubs has done several runs of reproduction of this style for the BBB.

I think they sound great.
