Steve:
I am not sure if it had a 6223 crank. I asked specifically on the dimpled rods and pistons and he told me the shop that is rebuilding it told him they were just standard oval port but the crank did not have to be cut and was forged.
Also the air cleaner never had a 345 hp or 390 hp decal on it, just 454 and that was original. It was a fully loaded impala that my grandmother remembers was a salemans demo with 2000 miles on it when they purchased it in early january of 70. So it was a early production.They wanted the big engine to pull a camper.
The car was loaded with air, ps,PDB, tilt, PS, PW, PL, rear defrost,8t,posi, fender skirts, delux belts,remote mirrors, etc.
