Engine Block webbing?

[Seventy4Blazer]

I got a friend that has a 69 Comaro SS. he is getting ready to sell it and asked me to time it for him. it is SUPPOSED to have the origonal engine in it. i have not gotten the numbers to run them yet, but a few features on the block have me wondering. it has a large webbing on the front passanger side of the block just above the timing chain cover. i have never seen this before. it also has the oil pressure in the front and the back. i am told that it could be a 283? or a 350 or a 327. with those two features im guessing it isnt enough to help. but i couldnt read the numbers without a mirror. so i have to go back. any ideas is VERY HELPFULL!

Get the suffix code off the block. That will tell you everything you need to know.
