Default Engine stalls when revving

Recently got back my sbf from machine shop , had it stroked to 347
Same time I changed heads, cam, tconverter
Re assembled the components , engine fired immediately broke in the cam
And every time I rev the engine 2500rpm + it bogs down then Stalls

I've replaced wires coil and even the dizzy
I chanced springs to bring timing on earlier
I've changed the fuel pump, I have a regulator and gauge showing its working

I'm still playing with the timing, as I'd like to get smaller bushings for my msd mech advance
I have not got a vac reading on it yet, that's my next step, but I have ensured no leaks

What do I look for next? I'm f*#%king baffled

Here's my build so far
Thanks for the help, appreciated
