While bored and unable to work on any projects i started thinking and that's where most of my problems begin. I know a lot of math is involved to actually figure out design but in theory longer intake runner length and exhaust runner length favor lower rpm power. the part i cant find is would this lower the camshafts advertised rpm range, or just make more power on the lower side or that rpm range. Ive head increaseing displacement (specifically stroke) will lower a given camshaft rpm range.
