70 318 with 340 internals/Cyl Head
So the answer would be.............323 cubes..........possible very low compression, better crank (good for 5-7 psi?), could possibly be bored to have a 340 piston, if not would require decking and/or some upgraded pistions to run well increase compression. Better flowing head than a 318 stock piece with 2.02/1.65 valves.
Is this recommended other than the comp concerns?
Not asking for hp estimates, usage projections, convertor sizing, DCR, etc, etc, etc.
It is what it is. It in the car. Here is a photo. Basic SBM. Some may be able to id the head, not me. That will happen Wed's and I'll have a comp gage in hand.
