351 windsor oil pan questions

[trash]

Hey all, its been a while. I have some questions. Im building a 69 351w stroked to 414ci . I need a rear sump oil pan that will use a 2 piece main seal.
Does it matter what year pan I use?
Will a pan from a one piece model work with a 2 piece seal?
This is going in a 71 f100 with a crown vic front end.
Thanks in advance Ben

I was under the impression that all 351 oil pans were the same, but I don't have any experience to back that up, I used a 1996 engine and pan from the same truck.

I could be wrong, but I don’t think Ford ever had multiple variations to the small block. Oil pans do come in at least 3 variations, front sump, rear sump and double sump.

Kinda late to the party, but what I'd use:
