I like saying I have a Mopar when people ask , "Hey man is that a chevy 350?" I look down at my feet and shake my head in disgust. Nothing wrong with the chevy but its just every v8 wrangler has them. Advantage to them is the TBI setup, but I have that on my 360la I put together myself.
I re-searched and saw that Mopars produce the most heat while chevy's produce the least. So cooling is more of a major factor on the Mopar.
If you plan on building the engine, chevy is A LOT cheaper to do.
I guess if i were to do it all over again I would go with a 351W or do a LS1...but not a 350.
