So I see people suggesting to put together a smaller combo in a BBM.....505, 512, etc.....The 440Source kits for BBM's are the same price for the smaller kits to the biggest kits.....So a 440 block can go to 541, and a 400 block can go to 512....In a big B-body, the 400 based engine will look small in there. So go big and bring extra money for new rear tires!
