Need Help on my motor

[silver00v6camaro]

Okay here is what i have planed to do to fix what the moron built me for a street motor. The bottom end is bored over .30 so i have a 355. the builder used my l48 heads and a edelbrock cam that requires at least a 3000 stall. so I am going to go with this
350 chevy bored over 30
GM vortec heads
770 Holley Street avenger
Edelbrock Vortec performer intake
a lunati voodo cam specs:
Basic Operating RPM Range: 1,000-5,500 RPM
Intake Duration 050 inch Lift: 213
Exhaust Duration 050 inch Lift: 219
Duration at 050 inch Lift: 213 int./219 exh.
Advertised Intake Duration: 256
Advertised Exhaust Duration: 262
Advertised Duration: 256 int./262 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.454
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.468
Valve Lift with Factory Rocker Arm Ratio: 0.454 int./0.468 exh. lift
Lobe Separation (degrees): 112

I need to know what a good tq convert will be or will a factory one work.
What are you thoughts on this setup. good or bad. any advice is appriciated
thanks

not being a tranny specialist, but observing your motor is very close to what mine is, the torque builds rather rapidlyafter 1500 rpm and your intake manifold and cam will die at 5500rpm.Also your .468 lift cam is the max for the vortec heads without some machining and different springs .Personally, I would use a stock converter stall speed. If you give me all the cam specs (intake centerline, opening and closing point s of the valves, etc.) I could run this engine on a simulation to see what it makes. Assume you run some kind of aftermarket headers with mufflers?

I agree w/ Curtis ... the stock convertor should be fine w/ this cam. If you have new lifters & new rocker arms ... please use new pushrods between them ... $25-$30 new set will be fine.

What is a guess on the hp/tq of this setup.

Sounds like a pretty solid 300 hp 350, probably 370-380 lbf . I dont think you will be disappointed.
