69' restoration

[69Z28-RS]

Ok will do.... Was anyone able to make heads or tails of either numbers I gave previously? 3744463 I got of the motor in the car and was located just behind the carb. On top of the motor... The other motor not in the car I found two numbers 8896948 and 878444... Both motors were pretty dusty and unfortunately I do not have a garage to keep it in so I have it stored at my grandparents so it may take me a few days to get the correct codes, since as you said it should be a alpha numerical code... Thank you guys for your help and reply's I appreciate it!

If you found the numbers behind the carburetor, those were intake manifold casting numbers...
