Looking for any info on rad/fan combo that someone has put in a 48-53 3100 truck using an LS engine? Another question is the frt of the engine pulley system used. I plan on Vintage air system so room is most likely an issue with routing of belts. Several sources offering different arrangements of pulleys to accommodate but I hoped someone might have been down this road and could offer suggestions. Any help/suggestions are greatly appreciated. Thanks!
