The small journal crank is not as desirable as the large journal crank but it will work OK for a mild daily driver truck. There is a reason Chevy switched to the large journal crank in 68, it is more durable.

the small journal crank will wind up a lot faster vs the large journal. this is the type crank dad and i had in our 67 camaro we built together. had 202 angle plug heads on it with a 750 spread bore. was a fast car and would roast the tires all the way through 3rd gear and chirp them in 4th. had a hallabrad quick change in it also and we were going through muncie rock crushers about every two to three weeks at the strip. IMO if your gonna build a 327 use the small journal crank as it winds up a lot faster than the large journal due to the weight difference. put a decent set of flat tops in it and a mild cam and you can make it tote the front tires in a daily driver if the top end is done right.
