I'm going to be building up a small block mopar engine. a 1971 318 block. I have big plans for it. My goal is to get the best fuel economy with the most power. Simple and I know, that's everyone's goal. But my question is, as far as getting the best fuel economy, where do I want my powerband to be in relation to my cruising rpm. Should I design with torque in mind or horsepower. I plan on doing two rebuilds of it. one, moderately superficial, durring which I will be adding fuel injection, headwork, maybe a custom intake- but not much internal unless its absolutely necissary. The next summer will go deeper and possibly look for a possibility of turbocharging it. I've got a heavy car, but looking at what other people have done, I can use their experience as a guide of sorts. so my questions
how should I choose to build the engine in terms of cruise RPM and power for the best fuel economy. is it always a case of, lower rpm, better mileage, where would the limit be.
also I'm aiming for the range of 300-350 horsepower, which is attainable from a 318, but If i fall slightly short I'll live.
thank you in advance
