Additionally, I want it all. I want mpg, speed, and plenty of power. I won't run headers, aluminum heads, or a stroker. I'm tired of chasing the supposed latest "best" thing. I have no problem making power with factory cast iron heads, forged cranks, on any block I choose. Think of a stock class race engine with a street cam, usually a custom Racer Brown solid flat tappet. I run full exhaust, since I sometimes drive at 70-80 mph for 12-15 hours a day. Not fun in a race car. That is my thinking.
