Just a quick question on dimensions. What are the spec differances of a 327 crank and a 350 crank,also what is the stock rod length of both ?
Thanks in advance.

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).

i don't have manual here (500 miles from my garage) but i think the 327 SJ pins are 1.998 a nd the mains are 2.248, or .200 smaller than LJ cranks rods are 5.7 length stroke is 3.25 for the 327 and 3.48 for the 350
