I don't have the numbers in front of me, but in '68 & '69, 327 bearings were identical to 307 and 350 bearings, referred to as "large journal". The '67-earlier 327's had the same bearing size as 283's, known as "small journal". The 307 and 327 stroke was 3.25" vs. the 350's (and 305's) 3.48".

All had 5.7" rods from the factory (journal sized varied, of course).
