Engine VIN Question

[m125x]

Hey guys, with my 71 Charger I got two engines, I was wondering if you could help me decode what they mean, where they came from, what car etc. I know they are both 360 engines and I believe that the first one is a 1978 and the second engine is a 1986. Thanks for any help!

First Engine (that one we will be running)
4006380-360-1

Second Engine
4179930-360-5

I looked up the number 4006380 useing this decoder. 1959-1978 and could not find a match.

This is the one... I typed down the wrong numbers

4006830 360 1976-1980 (LA-series) So what does that mean...

[brock]

Cool list!!!
Anytime changes were made to a casting a new number was assigned.
As for which year vehicle they came out of (440s have the prod date cast into the right side
of the block) how did they do small blocks?

[superduperbee]

Check the side of the block just above the oil pan rail.

I'll see if I can get some pics up of each block.
