ego, haven't been on this forum for a couple weeks, so just reading post. what are your expectations for f-1? v-8 will give more horsepower but not necessarilly more torque. is 6-cyl dead? if truck is daily driver/toy either engine will suffice. will 3-speed be enough or will you need a LOW 1st gear for working truck? you can find some exellent trans info in 48-60 forum
