Well, the reason I'm asking is because I'm in talks with a guy about buying his block. Unfortunately he's on opposite sides of the country from me. He said his block is a 56 261 with the above mentioned casting number. However, he claims that it's a full flow block, and is also in unaltered stock condition. That's why i'm confused. An unaltered 56 block should NOT be full flow, according to everything I've been told. He has no digital camera, so he can't just e-mail me pics. He said he'd snail mail'em to me though. Maybe he's not fully aware of what I meant by full flow. Maybe he thought I meant "full pressure" as in the second generation 235's. I don't know. I guess I'll have to wait and see what his pictures look like.
Thanks.
Josh
