Ok, I didn't know that. I do know that my '68 truck 327 is the same block as those two. So, this settles many debates over 4-bolt vs 2-bolt. It all depends. You can actually have a better 2-bolt block than most 4-bolts. These are high nickle and very desirable for performance builds. Mine was done in '07 and I forgot whether it was 2 or 4-bolt. Guess I remembered wrong. I can sort of remember seeing it was a 2-bolt now that we're talking about it. So, relatively speaking, these '68 large journal small blocks are fairly rare being one year only and 47 years old, last 327,first 350s, and the elusive 302. Rare and desirable
