ok guys, i have found a motor out of a 84' caddy with less than 80,000 miles on it. it is a fuel injected 400 and has belonged to an older gentleman. how much would be a fair price to pay for this motor and what details do i need to know to drop it in my blazer (conversions,different motor mounts, etc.) and is there any draw backs to this conversion. other than this motor i have found 2 305's so i think this is my best option so far.let me know asap please thanks. darren olander 1979 chevy cheyenne blazer 350/350 (dead) gettin' down on all fours 4 a'little x 4 play !
