Yes, BUTTTT,
At over 240 degrees at 50 lift it is at least 0.040 short on lift compared to modern grinds. It is by no means taking advantage of the 0.904 lifter. Take a look at the Hughes cams for what can be done with the 0.904 lifter. Or the Comp XE HL series or the VooDoo cams which seem to have different lobes for Chrysler cams.

The other thing to do is GET RID OF THOSE HEAVY PISTONS! You are building an engine with high rev valvetrain and head capabilities, get the reciprocating mass down from 1100 grams with pin to around 750 grams with pin. That's 350 grams, about a pound. At the top of the stroke where acceleration is highest, you are looking at thousands of Gs. That one pound "weighs" thousands of pounds at that point.
