The peak tq of a 273 2bbl was factory rated at 260lbft at get this... 1600 rpm. I am looking to keep the rpms low for this reason. I am also trying to figure ways to make even more tq at a lower than stock rpm. Even with this high gear combo I will still be OVER the peak tq at cruise speed of 70mph so don't get your pannys in a wad and say I need more lower gear ratio. Just trying to come up with creative ways to make this happen.
