George,
Throughout this forum and with all of the vendors, the general opinion is to use a four core or aluminum tube radiator for the 64-67 GTO's for overheating problems.
With what we all NOW know about the proper way to set up clearances for the water pump divider, Do you still feel the need for a larger radiator than the stock three core unit?
As someone that was a Pontiac dealership technician in the day, I do not recall a continual problem with overheating engines due to radiator size. Circulation problems yes. Largely due to excessive divider clearances as you have time and time again have posted about.
It bums me out since the stock three core radiator insulators are no longer available(AND I NEED SOME) because the assumption is that most convert to the four core or aluminum radiators.
What do you think?
Joe
