74 vette with a 72 Z28 block question

Hello from Texas to the Camaro owners....

Maybe you all could give me some help. I do not own a Camaro, but pulled the matching #'s engine on my '74 vert vette and am going back in with an AR Racing 355/427HP Dart head engine that happens to have a '72 Z28 block.... or it appears so. The block casting is 3970014... date coded A26 72 and the I.D. pad is stamped 10214CKA. From everything I can see it probably came out of a 72 Z28 Camaro.

The question I have is about the oil pressure sensor on the blocks of 72 Z28's. My 74 engine had a threaded pipe right above the oil filter that attached to the oil pressure sensor. This block does not have that. Where exactly is the oil pressure sensor on your blocks? It would be appreciated.

Here's a pic of the engine that is about to go in just to let you see what I am working with.

Drivers side top next to the distributor on the same surface as the intake aft seal.

if it were an engine out of a 72 z28 it would have had on the pad on the passengers side infront of the head a number letter sequence that ended with ckt (auto) or cks (4 speed). dont really know what a cka is out of

CKA is a 350/165hp engine with a 2 bbl carb. No Z28 engine there.
