Traded up to a 40 ford coupe and am looking to do a bit of spring spruce up to it. It's running a stock flathead and is in need of a new radiator. I have decided on a champion radiator, but I am not sure what pumps to get. It seems to me speedy Bill has been the go to guy for most folks. The bob drake units seem to have the same features as the speedway pumps but are a bit cheaper? Any opinions?
