413 vs 440??

theres no point in that. the forged crank is only marginally stonger (but ALOT heavier), and the 915/906 heads showed only minimal improvements in flow.
with that said, treat ANY used engine as a core..and pay accordingly. I offer him $300 and have a nice day.

I guess I should have been more specific in my answer, it's not about the crank, it's about the comp. ratio. A pre 71 440 will be at the higher numbers (10 to 1 give or take) therefore the gentleman may not have to replace the pistons or do any deck work. A re-ring and hone may, and I say may, suffice.
