pump gas engine vs. high compression

StrokerScamp said

Throwing out "you can run 10:1 with iron heads" is a really vague statement. Without building a very specialized engine (exspensive) you cannot. 9.2:1 is about the limit for an untouched combustion chamber without quench. But all that's a whole nuther arguement. If you're worried about the price of gas at ALL, maybe you shouldn't even buy a race car.

I posted this as an effort to educate myself on a subject I dont know enough about, before I spend my money. In the past I have found this to be a sensible way to do business. My question was not wether or not it was more economical to run a pump gas engine. My question or more acurately part of my question was if the fuel cost was the only reason to consider running a pump gas engine.
