Thanks Terry, Me too! Thanks Clayton. I'm guessing that this twin turbo setup on the 6v-71 would have around 500hp. (guessing) We used to tractor pull with some folks that pulled Olivers with 3-71s on them and they got some awesome power out of those without turbos and not turning over 2500 rpm. The tractor pulling association banned the 4-71s because nothing could touch them. So I'm hoping that it would at least pull a small camping trailer out of a mud hole, in winter, up hill. (LOL) But even if it has to be towed with a chain it's going to look cool. Thanks again Mike! You've been a big help! Thanks again for all the comments guys!!!!
