I don't recall any of the w engines I've worked, having the oil shield. But I've only worked on about a half dozen.
I don't know Phil, I believe all the ones I had apart were truck or industrial engines, but who knows their history.
Bungy,
Here are the codes:
Block
3751872 casting No.
G1158 date code
T317G front pad No.
Head
3732791 casting No.
B2158 date code
Intake
3732767 casting No.
A2458 date code
It appears I may have a later 58 truck block which still doesn't have the cooling holes. With earlier Heads and intake. It came apart this way so I'm putting it back together this way with a 340 horse 409 cam.

He's correct,it's the 229 th day of the calander year.That 811 block is best considered as a universal block that was used for the short period of time between when the very early 872 block and the later 5011 block. This block can be used with either the 791 head or the 379 head with no changes.If you want to use either head you can just bolt them on and go.If you're using the 379 or later head on this block and get the full effect the spark plug cooling,this block has provisions for the holes to be drilled.The 872 does not.
