318 300-350 hp goal : now 323 cu.in

Id go something like that cam if he goes 3.23, but if goes with 3.91 especially with 4 gear Id go bigger, with 3.91 and 4 gear don't need a lot of bottom end. Yes 318 needs more rpm to make the same power as a 360. But were probably talking a peak of around 5500 rpm for 350hp for a 318 and with a xe262h cam probably make 325 hp at 5200-5300. Not exactly a high rpm screamer for either.
