Hi all, Does anyone know if there is a difference between the radiator (automatic transmission) of a standard 350 engine and a GS350 315hp engine builld 1970? I see Rockauto.com supply at the moment only 1 radiator for the standard engine: Ultra-Power 161. And for the GS350 are 3 economic radiators: TYC 161, OSC 161 and the same Ultra-Power 161. Does anyone experience with one of these? I don't want to bent or change any automatic transmission pipelines for to make it fittable. I have a 1970 GS350. Also I can buy here a used one on Internet which is from a 1970 Chevelle with a 455 engine. Would this fitt properly or a radiator from a 350 Chevrolet? I am also looking a distribution cover because mine is cracked again after welding it. Which ones are recommend for a good price?
