I'm having this same dilemma in my head right now. My old motor is tired and I'm getting ready to drop in a fresh motor. Currently I have the SM 465 in my 71 4x4 K20. I was thinking of getting around a 300 hp motor for it, but am thinking if the Hp will be useless behind the 465 with the long throws and big gear spacing. I have been saving a Turbo 350 and NP 205 setup if I do want to convert it to automatic behind the new motor.
