10 sec. 318?
Make sure the frame's tied up, suspension is set on kill, take all the extra weight you can out of it, then it's motor time. I'm no genius here but I do know that ten's is no easy task especially with a 318. I'd say the absolute limit for pump gas compression, some kind of worked aluminum head, forged internals, good intake and cam, some kind of HP douable pumper carb and maybe even a 175hp helper. . . just sayin, sprayin is easy.
