I recently went to my local junk yard need some original bolts for me 64 330.
I believe its a HC it still has original rock. 4bbl carb any way my question the harmonic balancer is different on this 64 330 then on mine mine is a LC 2BBL is the reason its a different HB cause it is a 2 bbl the outer circumference is smaller (where timming marks are ) then on the junk yard engine or is mine wrong , about 25 years ago I has someone change the timming chain and found out much later that there was parts (mostly bolts and washers) missing
