I'm putting in a 455 ci engine into my '66 skylark and I'm concerned about engine cooling. The radiator is fairly small. I did find the following 4 core aluminum radiator: https://www.amazon.com/gp/product/B077BWD4ZP/ref=ppx_yo_dt_b_asin_title_o02__o00_s00?ie=UTF8&psc=1 It's a 4 core with a built in shroud. I was also going to add an external transmission cooler and not use the one in the radiator to help the radiator be more efficient. Will this work? Does anyone have a picture of their setup? Any suggestions?
