THats what the midget guys were doing. Putting a small block Fuely head on them and you suddenly had a screamer.A neighbor of mine had one in a boat. He stroked it to 3 liters I think, And I tell you what it was a real ripper. He may have even put a small block Chevy head on it as I remember that wasn't that hard to do.
There was an issue with the large (2.02) intakes getting into the top of the block, so a relief had to be cut there for clearance and the loss of compression from that made up with the dome on the pistons. The CR or a methanal eating Midget engine was insane.
