Direct Replacement Aluminum Radiator

The answer is tube to fin contact. Brass copper is relatively soft compared to aluminum. What this means is the tubes in a brass/copper radiator are limited in length to about 5/8". Any bigger and they would balloon from the pressure. Aluminum, being much stiffer, allows tube sizes up to 1 1/2". More tube to fin contact area, more cooling. My Griffin radiator (I was told), with 2 rows of 1 1/4" tubes cools the same as a 7 row brass/copper

A totally correct response.:TU:

I forgot to add that Al radiators are lighter weight (25% I think) than their copper/brass counterparts.

My Vortech YS Trimmed 455 runs at 165 degrees all day long with a stock four row and fan clutch. I live in San Diego so it does occasionally get pretty hot. This car also made 814 lbs of torque to the rear wheels about 1 month ago so it is no slouch.
