Hi, I’m an amateur and I have a small block Chevy engine mounted to a transmission. I have a 1949 Chevy truck 3100. The sbc has no casting numbers, either rust or oil is covering the numbers but a few people told me it’s a 283 or 327.

The driver side numbers on the transmission is GM 3925660
The passer side numbers are 3925660 and right below it is

US patent No 3088336 general motor corp

I want to buy a new engine or rebuild my old one so I’m trying to figure out the transmission

Can you post pictures of your engine?

Can you post a picture that shows the front of the heads? Also, if you pull a valve cover the heads will have casting numbers and date code cast into each head.

If the trans is a Muncie, more than likely the engine is a 327.

Yep, that is correct.
