14" fan + 360 = overheat

When I got my 360 out of the yard and tore it down, the water passages had a gritty pudding in it....I ttok it to a place called 'Reddistrip' in Allentown. That sucker looked brand spankin' new. Most of the guys around here take their blocks there for cleaning before machine shop. I'm going to use a Summit Alum radiator and trans cooler, stock shroud and 7 blade fan. I should have no problems cooling.
