The 2bbl brought it up to 142 net horsepower then with more improvements for 1966 to 157 horsepower. Possibly mileage may have been why a 1bbl was used. Originally the prototype trucks used were lighter 1958-59 trucks and the 1bbl version was more than adequate.

Ah, Ok. I watched a video of a 305A running...man you could hear that thing Breath. lol I was like yeah....that carb is a bit small. You know what improvements were made in 66? I remember running the numbers on mine with a fellow forum member, and my 305 in my 64 looked to be a 67 series engine. Did the 305E ever come in medium duty trucks? Cause mine had the governed dizzy on it.
