1973 340 and 727 in NE Pa. $1,500

Mike, the first number is hard to see, like it's only the bottom half of the number, but here it is

5R208300

The date on the block is 9 27 72.

I also noticed that the bottom mounting "tab" on the block, right behind the starter, is cracked. You could see half of the threads. This is where the block meets the transmission. I never noticed it before because when we pulled the motor, I loaded it in my truck, unloaded it in my garage, and covered it up. I called a local machine shop and they said it should have no effect on the engine sealing with the transmission. Like I said in the ad, I rode in the car when this engine and transmission were in it, and it was fast and ran like a bear.
