Hi guys i'm a middle aged woman in chicago IL that just received my fathers 1953 gmc 1/2 ton pick up a gift. The body is in great shape and partially restored but i'd like to use this as my daily source of transportation. The expressways around chicago require I drive more modern speeds and gas mileage is a concern. I'm planing on using a S10 frame and updating the drive train. Since i'm starting from scratch any suggestions on engine-transmission-rearend for my needs? Thanks for any help!!!
