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
