Trans cooler

Everything's relative for sure.
Lots of engine transplants/upgrades might require a radiator upgrade as well. Lots of aluminum upgrade radiators don't have tranny coolers unless they're a bit custom. Therefore you might want an external tranny cooler as 1972 Demon has. Nice job there by the way. My 67 was a 273 car upgraded to a 360 magnum with a new be cool radiator installed without a built in tranny cooler. It now has an aftermarket aluminum combination engine oil and tranny cooler installed in front of the radiator and works pretty darn well. If it doesn't have a radiator with a built in cooler than it should for sure have something external if you want to keep those temps reasonable in our hot rod world. Just my opinion of coarse.:burnout:

Great chart there Tantibus.
