250 inlne 6 oil pressure port
 

I recently installed a rebuilt 250 from a local rebuilder in a 66 C10. It runs great but it did not have an oil pressure port in the block. Has anyone ever seen an inline 6 like this? Is there another oil passage, in the head maybe, that I can connect the oil pressure gauge to? The casting number on the block is 3994257.

Should be a port right behind the dip stick tube. Maybe it just has a plug in it.

This should give you an idea. It is down on side of block near dipstick tube. I stole the picture, but mine was in same location

Thats where it is on the old block i had. I just took a picture of the new block and i see the plug. I dont know how i overlooked it when i was assembling the engine. Thanks so much for the responses.
