Is this your 340?

Whew! thank goodness you found my motor(s). I'll send UPS for them. I don't have proof that they came outta my 72 /6, I mean 340 duster, but you'll believe me, right? I can identify it by the amount of cylinders. I'll PM you so that no one else can try and steal this secret information from under us. What a good sam you are.

you're funny, a regular Jan Murray!
