Knocking 340

So the 340 is back with the Engine Builder. he's gonna tear it down and have a look to see whats what. He has a dyno so potentially I'll get it on there before it comes back to me.

I have a little update on the re-build specs, but not much. KB Pistons 40th over. Has a Comp Cam, but as of yet Im not sure which one. Stock X Heads, Ive a brand new Firecore Dizzy for it and as Im tight on the budget I picked up a brand new Holly 750 4160 for cheap thats whats gonna go on it just now. The engine builder does not wanna mess around trying to tune a used carb and I cant guarantee the 670 Street Avenger I have on my other 340 will be good enough for him.

Anyone willing to take a stab at hoe much HP and Torque I could expect out of it? :D
To get a rough figure on the HP you will need to have the calculated compression ratio and cam spec's.
Will the engine be stroked? Any head work?
They are members on here that are dam good with power calculations.
Me not so much.
