That's true, I was thinkin about puttin the info on the 2.73's, yes the 305 made a small amount of hp more and could therefore use a slightly higher gear ratio. the 305's are ither 125Hp or 145Hp and the 267 is 115Hp. theres only a diffrence of .35 in the gear ratio and 30 hp ( rated from 145Hp ) so it basicly is equal. I did those numbers as a theory really quick so, I don't know if they mean anything.
