Help me decide: 360 or 400

Lol I have the same situation!! I have both a 360 4 bbl and a 400 4 bbl. Trans for the big block but none for the sb..but have a stock 360/904 tq converter..Anyways I chose the 400 because I also have all the 440 internals to build a 451.400 fits better than an rb,not as easy as a 360. Put enough aluminum on the b block and the weight is as low as a sb or close enough.Pro's and cons to both. Your budget is gonna dictate what you choose...
