Hi all. New member, first post. Am involved in circle racing with old time cars. Are turning a 250 at 6 to 62 on 1/4 mile track, with a single barrel carb as that is the limitation. Also CI limit is 310. Need to build new motor this winter and was wondering about the 270, or did the four main crank pose a problem. As a kid, I can remember that they were very dominate, but that was then.
Any opinions would sure be appreciated. Thanks
