I remember in 73 reading an article saying that Jenkins' 331" SBC in the vega was dynoing at 585 hp, considering the Iron heads of the day that's still pretty impressive.

I remember Darrin Morgan saying that normally aspirated the limits of a 2 valve engine iwith today's technology s approximately 1.65 lb/ft of torque per cube (and 1.3 is generally considered a very good street engine), but it's unlikely the wedge (or many any other) motors of that time were anything close to that.
