Ok, This has been bugging me for a long time and I have to start this post. Let me explain what I have in my books. Ok we know this:
The 350 was first introduced in 1967 in the Camaro. The engine block casting was 3892657 and according to my book was 1967 only and was used on 302, 327, and 350.
In 1967 the Z/28 302 was a one year only small journal crankshaft and very rare.
In 1968 they changed the Z/28 302 to the large journal crankshaft and used a different engine block as well, casting 3914678.
In 1967 the 350 was introduced and the crankshaft was a large journal. This again was a one year crankshaft and all were forged steel. Also, noted that this was the only large journal crankshaft offered in 1967.
So, how did they put this large journal crankshaft in the very same block casting number that is a small journal block? Did they just machine the block and main caps to accomodate the large journal crankshaft?
