318 f.a.s.t class , oem stock appearing

Still wondering how a powerfull 2bbl stock stroke can run or even stroked to 390s with a 2 bbl can do , never heard or seen something like it

I think the manifold and carb would choke it bad, also they have a a ton of money in a full race rollerized 904 trans that knocks half a second off of a built 727 and even more off a manual trans
