The d0ve 460 was pretty much the best set-up out there. These motors were used from 68-71. They had 10.5 o 1 compression, 365hp/500lb tq, 2.06" intake and 1.65" exhaust valves. These engines were monsters! After these years the ratings went down and within like 4yrs the 460 was under 200hp. That is the info I have found on them, I just started searching on them since this is my first one. I have always heard of them but never seen one.....till now!
