He doesn't need an intake for a 4500, here's a pic of a 1050 that's not a 4500 and will bolt right on his intake.
Reality check here: You cannot compare a 1.58" v x 1.75" t 4150 "1050" with a 1.72" v x 2.0" t 4500 "1050". Doesn't matter what the carb company labels it, it's not an apples-to-apples comparison.
And, yes, I have something like that, too, and it was good enough to make about 680 HP w/ my stock-stroke 440 build.
