While true the 400 is stronger. They can indeed break too, I broke a couple myself in my early years with 5000 lbs cars and big block engines.
As for being cheaper yes but if you drive the car much at all any savings on the build are quickly eaten up by the 30% or more fuel used than you would with the 4l60e and this is only accounting for the ratio difference add in the lack of lockup and a big stall and its will be considerably more.I would never do a 400 swap unless the car was a trailer queen or a weekend track warrior only.
Its like this what if I told you I was gonna build you a 60e really cheap but wanted a $50 dollar a week surcharge forever on it , Would you really come out cheaper? Not to mention your engine is wearing at a 30% greater rate. Alot of people misunderstand that milage is meaning less without other information. A car for intstance with 4.10 will wear the engine at a 30% greater rate than the same car with 2.73 make that a car with a 3 speed auto and now your near 60% .Just and IMO.
