Question:
I am building a 49 Merc with a stock 454 chevy engine with a 400 turbo transmission. I need a transmission cooler and was interest to know if the 20inch dual bypass cooler would handle this application. Thanks

A lot depends on how much power you plan on producing with that big block and how big of a stall you are planning on using. Some stock 454's aren't crazy powerful, whereas others like the LS6 are very powerful. With that being said I would go with the absolute biggest cooler you can fit. Also, stacked plate coolers are the most efficient style so I would lean towards one of those as well.
For example, the stacked plate cooler part # D13403 would do an excellent job for you so I would recommend it. This cooler is 13" Wide x 7-5/16" tall x 2" deep and would need to be installed in front of your radiator where it could get as much air flow as possible.
I attached an FAQ on transmission coolers for you to check out as well.
