Cast Iron manifolds on Super Stock cars

[Rory McNeil]

Or fourth, it may have never been raced as a Super Stocker at all. I see so many "race cars" at shows, that have never seen a dragstrip. But I have seen plenty of poser cars , belonging to guys that think a few stickers are all it takes to have a "race car". Seen way too many 64 Fairlanes with a bubble hood, and "Thunderbolt" and "427" stickers on the sides, with a small block under the hood. Kinda like the hundreds of 67-69 Camaro "Z/28s" with automatic transmissions, and a 10 bolt sitting on mono leaf springs.

Those factory cast iron header/manifolds are not to shabby. A few years ago when I was doing Tech at Engine Masters Challenge one of the participants made some respectable pulls with a 406. He changed from his tube headers to a set of the shorty 427 Ford cast iron manifolds/headers. His power didn't fall off that much (6500 RPM limit) and the Tq actually went up at a lower RPM. Pretty good design for back in the day...

Seems to me that cast iron header type manifolds were around back then. I remember seeing some 390 Ford Galaxies,around '62-64 thaathad a good looking set of manifolds on them. The regular rectangular exhausts like a 352 or a standard 390 had weren't too much to talk about, but the cast iron headers were pretty interesting. '63-64 400 horse and 425 horse 409's had a good exhaust manifold, so did 421 Pontiacs. There were others as well, but none of the cast headers could compete with a good set of four tube headers.

Some those early Pontiac manifolds were aluminum as well

You guys did notice how #5 and #7 are split here, right?

And they melted rapidly. Pontiac didn't have a good alloy for them . I had a few sets. Melt under the bolt head. Guys would retighten the bolts, squish the flange, loosen, retighten, melt, squish, retighten until junk. Sad. Because the cast iron ones were 78 lbs apiece.
