Thank you for all your suggestions and help. My radiator is currently a 2 core. My newest question is - should I continue with a 2 core or go to a 3 core? I do not have AC or power steering, and it is a manual transmission. I am clueless about the differences regarding the number of cores needed. Thank you in advance.
Look for a two row with at least 1" cooling tubes. The ACP Max core is a really good radiator also for less money The ECP radiator is a great value. I have the ECP in my cars.
