UR 2 Slo: i think you have a Cool truck..5 window too...You probably will have a better time putting a 235 in there..just about bolts right up...But a 350 would get you there faster..i guess..Anyway you can start your Own business with that truck,,Im sure people would talk about ya with a "different" truck on the road..A better one then they make nowadays..far as im concerned..Old Chev's like that are pretty cool....Dave
