I want to get an all-aluminum radiator from Summit for my K5 Truggy. Question is, what size should I get? Over-kill kindset says to just get the biggest one they offer (31"x19"?) but my rig is narrowed and the hoods front is lower than stock, so if practical, a slightly smaller one could work as well. Question is, how do you know what size you need. My engine is a mild 350, fans will be windstar electrics.
