I've heard bits and pieces of stories of Bill Seebold running one... Anyone have pics or stories about T-4's on tunnel boats?
It was used to compete against the V-8 at venues where it met the rules.

There is something that I am trying to figure out about the history of Mercs "big block V-6"
In 1980 Seebold raced a Merc big block V-6 in Europe before the time of the V-8's. This engine did not have the T-4 cowl, just a plain black "300" cowl. Two years later Seebold went back to Europe and took on the V-8's with a 2 liter Merc and won! The "T-4" showed up later when the OMC V-8 series came to the U.S.
One of these big block engines had something to do with Cosworth. So, was the engine that Seebold raced in 1980 the same as the later T-4?

Merc subbed casting the big blocks to Cosworth the way Chevy had Merc cast the Corvette block in Oklahoma.
My notes say the first year of production of the T-4 was 1978, so it could be both the earlier and later motor with different decals.
If I recall correctly, Seebold's win with the smaller motor was with the aid of teammates a lap down blocking the V-8's.
