Practical limit on a 261. Hmmm. It's easy to get 200 hp with full race cam, dual two bbls or 3 ones, ported, polished & shaved head and either HEI, dual point or unilite. This is a streetable engine, too.

200 hp out of a 235 is pushing it. Yeah, the head is a problem along with rpm and crank balance. A cross flow head is the only way to really light either one of these up.
