Thanks fvike! Yes, the Ron Davis has a drain plug and as for the cost, it was ~$500. It's $750 with dual spal 12" fans. I'm not sure how much the BeCool radiators are though. BTW, the radiator in my car is a fox body Mustang radiator so I'm not sure how much a direct fit would be for our years (I'm guessing pretty close to what I paid)
