I run a PWR alloy radiatior in mine, and am happy with it. I would be running a custom made radiator, from Race Radiators, if I was about to spend $900 on a radiator though. I bought mine used.
I will be having some nice alloy 65-66 radiators coming in a few weeks though.
Description :
Features extra large 1" tubes for 4 row efficiency but with 5-7 lbs less weight. We also added a, Scott Drake exclusive, baffle at the top to help evenly distribute the flow of hot water across the upper part of the radiator. The original radiators had a real problem distributing the hot water to the far right side of the radiator. We have tested our design and recorded significant changes in the temperatures across the radiator's cooling tubes. A/T cooler included.
