Very High FE Dual Quad - What is it?

Not sure if it’s FOMOCO, but had that manifold on my 427 side oiler. That was on my Sanger Flat Botton boat in 1971.Interesting, that was at Tahoe and actually raced Shelby’s flat bottom “El Cobra”. Did win, however Carroll wasn’t driving!

Maybe it's taller for use in a boat and has a marine part number?

I've seen that with '80s Boss 302 and 351c casings intended to look stock on the exterior but were for undetectable racing interior porting. This could be one that escaped the laboratory.

Ahh..... you have struck upon one of Ernie Elliot's biggest speed secrets. They had new manifolds cast using the Ford exterior and and an entirely different interior. They like Bob Gliden would never share their engine development with the Ford engineers as they didn't want other teams getting the information.

Could this manifold be the cause of the bubble hoods on the Thunderbolt cars?

Why is Randy conspicuously absent on this thread.     

I thought he would know immediately.
