sorry for the dumb question. i want to order my radiator this weekend. i have it narrowed down to 2 options. i can get a 4 core champion radiator for 305 dollars. it has 0.63 inch tubes x 4 for a total of 2.5 inches. or a cold case 2 core radiator. it has 1.25 inch tubes x 2 for total of 2.5 inches. the truck is a stock k20. i need extra cooling because i brought the truck down to the desert where its 115 -120 all summer long. the truck is auto and has a/c. thanks
