Start a Debate

[ProTouring442]

Ok, I am trying to start a debate... but only because I would like to learn!

Totally theoretical; if you were trying to build a motor, say around 300hp that got good mileage how would you go about it?

For the sake of the argument, I'll make it more specific; we'll put our theoretical engine in a fairly light weight car, say a fox mustang. I think they weigh in around 3,200 lbs. We'll put a manual tranny, a six speed to get the double overdrive.

Now, would you build a 302? Maybe a 221 (smallest 302 style block) Sleave down a roller 302 with a 221 crank for a total of 221 and run a turbo? Maybe an intercooled supercharger?

I figure the 231 supercharged V6 in my Bonneville gets close to 30mpg highway in a heavier car, how would a 221 do in a 3,000 lb car?

Open up guys, get creative and technical, please.

Shiny Side Up!
