The facts are (and you know how much some are bothered by the use of facts) But GM has "stuck" with the small block because they have had no reason to change. The modern Ford V8s are and were so uncompetitive they were laughable. There is a reason the mod V8s were nicknamed 'boat anchors'... Because that's what they did best. And now, those small block V8s get better mileage than a Ford V6. Ever since the modular family hit the market, GM has been lightyears ahead of Ford engines. The small block is sunrise reliable, cheap to make, very efficient, compact, cheap to repair (rare), etc. The only competition GMs engine family has had was from the 5.7 from Chrysler. And as good as the 5.7 is, the GM small block is a better engine.
