Default 73 Coupe - Block code?

The engine components of this poor C3 has been butchered by the PO.
Trying to see if at least the block is original to the car. Don't know where to find the numbers on the heads.Name:  block stamp.jpg

Number on driver side where block meets bell housing 14010207 another stamping is 39 GM and on the passenger side K70.
Fan shroud number (just a part number??) 331889 and noticed these numbers on the firewall 48076.
Put them all together and they're all just greek to me!

Thanks for any assistance!

Looks like you have a computer carb on there. It won't idle properly on a '73. I'd be looking for the correct carb before I do anything else.

Your block casting #14010207 is for a 1980-85 Corvette 350, 190hp & up, 2/4 mains.

There should be a part # on the other side of the carb.

There should be a pad that is stamped in front of the passenger side head where it meets the block.

If you pull the valve covers you should find the casting numbers for the heads.

Yeah the carb and manifold are suspect. I HATE the aftermarket cheesy chrome stuff.
What is a "2/4" corvette?
Thanks for the help everyone!

I bet someone swapped in an L-81 or some other '81+ engine
