I thought my HP numbers were good, but now in looking back at dyno results in George McNicholls book they don't seem exceptional. He has one 259 in. conventionally aspirated street motor at 206 hp, a 286 in. carbec motor at 215, and one 260 in. street performance motor at 208 hp. This puts my 270 incher right in the ball park. Joe Abbin's test mule 286 incher ran 215 hp with a blower cam and 3 carbs.

Reallistically, no engine builder is going to give you anything but their best case scenario, especially in print. But all these engines producing within 10 hp of each other and having comparable specs does indicate to me that 200+ hp street engines are reasonably attainable. After the money I've spent on this engine, the will to believe is strong.
