Biggest baddest cam for Vortec heads?

Hey everyone,

Just curious what would make the most HP/Torque for this combo. The engine was made a few years ago and has very little miles on it. It was patterned after the HotRod magazine 440HP budget vortec motor with a few changes.

Chevy 383
9.3 compress .035 squish with D-dished probe pistons
Vortec heads with 2.02 vavles
1.6 roller rockers
hurricane? (fake edelbrock air gap rpm intake)
Hooker super comp 1.75" fenderwell equal length headers with 3" collectors
Cam is currently a XE-274H
Holley 850DP
3.73 12 bolt Posi
TH350
125 shot of nitrous

Its a street truck, some strip duty, 58 chevy flatbed not sure of the weight. I'm just curious if there would be a better cam for the combo? I think its pretty good as is but would like to hear opinions.

Your cam is already a hair too big unless you get port work done. Going bigger means going slower.
