I run a Morroso finned heat sink cooler on my bracket car. Been using it for about 25 years. I mounted mine near the transmission tunnel, just in front of the rear axle, and run strato-flex lines(#5) to it. Never had any issue with it or transmission over heating. 440, 727, Turbo Action "J" converter, running 10.50 1/4 miles times. I used to run two classes at the same events, but now just double enter same class sometimes, no problems.
