As of right now I'm just running a filter no oil cooler lines like the original 305 tbi setup had , but I live in the south it get real hot , I'm thinking about putting the oil cooler system back on. The orginal system for the 350 motor used the coolant to warm and cool the oil , my 1990 Chevy truck uses a oil cooler that goes right into the radiator . Has anyone swapped a truck radiator and oil cooler lines successfully and did it work well with cooling?
