Why is there 440source but no "360source"?

I get what all you guys are saying really, abodyjoe made a good point about the stroker kits which are definitely plentiful for SBs. When I mentioned the 440source Stealth heads it was mostly about the price I personally don't care what the outside of the head looks like. At this point at least I know and I'm aware of many others who know that most aluminum heads need to be gone through so it would be amazing to find a way to make heads with good machining to not require final machining by the guy using them and ultimately be more of a bolt-on deal. Lots of crazy technology out there today (and coming in time) who knows... what sucks is there ultimately aren't a lot of vehicles made after the A-bodies that came with small blocks which are popular for turning into hot rods. Maybe the '90s Dodge truck guys with Magnums but that isn't exactly a huge market either.

I like big blocks too but not if I'm building a smaller car that I would like to have somewhere close to even weight distribution :D
