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? |

Re: Engine Block code
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.
