someone look at my cam card please.
LS3 heads, 370 CI, TC76 (.96AR exhaust), about 9 to 1 comp, vic intake and 85mm tb.
The reverse split you have is a better match to the small TC turbo turbine.
Actually, with that small turbine a 216/216 would probably do what you want.
Any smaller and you might as well but an LS6 cam in it.
Your current cam is a better match to a GTS or bigger turbine. (75mm +).
The TC has a 68mm.
75mm turbines back up at 5k on a 350.
People run TC's on 5.3's.
The 68mm turbine is small for a 346 -period unless you want to shift at 5500.
More duration/overlap just lets the back pressure back into the cylinder
Never going to make more power at 6k with little turbine so might as well go small cam and pick up power off boost. Or get a GTS.
