Crank has a 2.84 stroke, about a inch less than a normal Pontiac 326/389/400 type engine. Crank will be light as most true 303 cranks were center feed cranks for the oil passages.
Rods are most likely a set of the Carrillo 7.080 type rods. I have some of them too for a 366 type engine. Pistons would have a "funny" set of valve reliefs in the piston top if true RA-V pistons vs 400 style normal valve reliefs.
