checked my notes & I think it shakes out like this....

The BBrown Roger Dean (N664890) car had TO512MN with C 12 9 and vin N650157? according to Ed C's inspection. I think Alan F sold it to you when he located the original (664890) engine. I remember trying to buy (the one that had been in the car) from you, but it had already been sold.

The TO521MN block was in the deal when Alan bought the Blue Mule from Dan. The date on that block 'may' be D 29 9. That block was found in the Newark area.
I have never seen this one in person, just referring to my notes. It would be a very good engine, date-wise for my Scuncio, even if it's not my orig engine
