I aggree with all the above, high compression ratio, small a-series (A10,A12) small carb etc. Use 0w20 synthetic oil in the engine. (low friction) How about the rest of the car. A datsun 5spd with the greatest overdrive ratio in 5th gear. Low ratio rear end gears. EG 3.9:1 or 3.08:1 or better. Run 75w90 synthetic gear oil in the diff. & trans. I'd run 12" rims and tires, as thin as possible 145sr12's etc. and run them at somthing like 40psi or higher for (less rolling resistance.) Run no front or rear spoilers (drag). Remove the outside mirrors, wipers & antenna (again drag). You could also tape all the seams with racers tape (hood edges, door gaps, etc (again, less drag).
