Depending on what comp. ratio you get with the 1.5 head, a 5 speed may not work well. You drop your rpm, but will it have enough power to pull an overdrive? Flat tops, at least, or maybe do the 2.4 stroker bottom with the stock head and a good cam.
I'd say look for torque rather than hp. Anything that keeps the rpm down will help alot. The further you have to push the pedal down to achieve the performance you want, equals more rpm and gas.

Keep the windows up, aerodynamic mirrors, 3.18 rear end, lose the roof rack, front airdam, and maybe lower it a little.

Whatever you do, keep from having rev the motor to much.

Maybe someone else can answer this, is there an advantage to using an earlier small runner intake manifold for economy purposes?
