I was looking for the mixed journal sizes here for my Jan 1967 built SS350 engine. Was surprised to see that this subject has not been confirmed yet.
After reading a previous thread (http://www.camaros.org/forum/index.php?topic=8402.0
) I became even more confused. The reason this ORG exists
is because GM didn't do well when it came to documenting anything in the late 60's. I was surprised at how quick some were to tell the previous poster
that the subject was closed for discussion. The mixed Journal crank does exist. I have one. My machinist here in Sacaramento knew it when I took it to him.
He just called it the ONE YEAR crank. Small main, large rod, journal crank. The previous discussion did not even mention that the MAIN CAPS are short as well as the MAIN BOLTS. The new main bolts I ordered are way too long. My block was still standard bore. (Casting number 3892657) (Date A97) (Crank Cast# 2690)
Original heads, intake, waterpump, alternator, ditributor, Starter. Balancer is a 6966 if that is correct?
So, as far as I can tell the block has not been rebuilt. (Still had the original paint splotches on the rear)
The mention that racers may have turned these cranks doesnt make up for the short caps and bolts.
Besides, if it was raced it wouldn't have ended up back in a bone stock engine. So that is out.
Also, how many people here with an original 1967 350 that THEY have rebuilt are the ones providing answers?
