Puzackly. The Road Runner cam to me, is one of the best all around street cams money can buy for an everyday driver big block. They just WORK. You're right. People put big intakes, bug carbs and big cams on low compression engines expecting them to run good. But they can run good if you are smart with your parts choices. Just look at that low compression 440 build Jim Laroy did. That's proof to me that power can be made with low compression. It's all in the heads, as Jim says all the time.
