Engine Block code

I have a 292 in a C20 I'm working on and since it's a 65 I know this engine prob isn't original, since it has a monojet on it. But, just wanted to find out what this actually is. Here are the numbers on the block:

35 88
GM 4.8 G
93411147

M0220PTA

Head stamp: 4886F8

I have figured out from research it's probably a 75-84 block from the casting #, and the date code tells me Feb 20. Not sure what the PTA is, it didn't show up in the chart.

Thanks in advance for your help!

Any ideas?

No good answer but some opinions - https://www.inliners.org/ubbthreads/...t&Number=62287
Everyplace I searched here and online say it's a replacement block from Mexico. Though no one can verify that with technical information.

Awesome, thank you. Seems about right, there's a rebuild tag on the driver's side of the block by the pan from Spokane. Explains a lot.
