I find it kinda sad when someone puts together a new combo and hits the dyno and ends up dejected with the results. See it here often. Then they immediately start thinking about changing out internals, never seeing what they’ve got after some time working on it.
I’d leave it as is, take it to the track and work on launches, hooking and shift points. See what you’ve got there as a package. The ability to put down good numbers at the track is more impressive than some arbitrary horsepower number IMO. 460, 500 hp on the street means nothing other than a number to throw out to impress.
But as it is the CR is kinda low, you could step up a bit on cam, intake, rear gear.
But you have the combo, you say you’re happy with it so work with it for the coming year, see whatcha got on the street and track
Then later maybe go with a 4.10 swap, try a nicely ported single plane intake.
You can always change those internals later as well.
