I will be installing a BB in a 70 Nova. Looking for some ideas about the radiator. I do not want to change the core support. I do not want to cut up the core support. I was thinking about having the small block radiator recored to a 4 row. Any thoughts from someone that has done this? I talked to Alumitech about one of their radiators, but at 500 bucks, I would like to check other ideas. Thanks.
