I don't think it will be as much about MPG as HP. A 318 with 7-7.5 comp and heads with big ports and valves plus a moderate cam would be seriously slow and not fun at all to drive IMO.

He said hes 17, more than enough engine for him rite now! When he wants to go fast he can just slap a supercharger on it.:thumbup:
