I don't mean to split hairs, but I am pretty sure 68 was a change over year, where some left over small journals were used, but the new large journal cranks were also in production vehicles. I own a 68 Corvette with the original numbers matching 327 and it has a large journal crank. The only true way to know what you have is to measure...if you need to know that info you are probably rebuilding which means it shouldnt be a problem to pull the pan.
