Will it be enough
Goal is 750-800 rwhp
LS3 Car currently has:
Si trim with 6 rib 3.8 pulley @ 6-7 psi
1 7/8 headers
made a little over 600hp on the dyno and trap speed in the 1/4 are low 130's
Plan:
416 forged and stroked
Ti with 8 rib 3.4 pulley
meth
mild blower cam
Is my plan enough to hit my numbers, or do I need to go with a lower pulley for the Ti?

ECS kits run a 3.25" pulley if I'm not mistaken. I ran a regular T-trim with a 3.4" pulley and a fairly mild cam (224/236 114+2) and made a little over 700 rwhp on my local dyno. I sold the car a while back and the new owner made ~730 with the same setup and tune on a different dyno. Obviously dynos vary.
I don't think 750 rwhp is a problem at all with a cam and 3.25" pulley. I'm not sure how your extra cubes will factor in, but I'd keep the compression very close to stock if you can.

Correct I'm running the stock ECS pulley which is 3.25 like he said but I still have a restrictor plate making peaking 13 - 14 psi if I pull the place I'll see another 2 psi or so & make another 30 - 50hp on a stock motor with stock bottom end, stock cam, and stock heads... So no i don't see a problem making 750 - 800 with built bottom and cam etc... ECS did my friends ls2 which made close to 790ish with stock bottom cam & blower kit with a novi 1500...
