Like was said above,..higher compression, larger valves, and 4 bbl vs. 2, made the diff between the 210 vs. 275 hp 327's.
But don't forget, even at 275 hp, that would be equal to about 220 hp at the wheels (20% penalty for drivetrain and accessory drag...today's cars hp ratings are measured at the wheels,..not flywheel as was the case pre-1972).
I know a few (ebay, etc) are lobbying for the 275 hp 327 HP to be held as SS's. I say no way. We're talking late 60's here,..not late 50's.
I'm not sure about the piston design, but LF7 was around 8.5:1 compression and the L30 had 10.25 if I remember right. I think the LF7's "power pak" heads had around 70-72cc chambers, while the L30 had smaller chambers.
