All Small Six Block Identification

[ladiesman217]

Hi All,
I'm looking for some help identifying a block of mine. It's a pre-efi 250 crossflow.

I purchased a series 3 range rover that was used as a farm hand. It came with a 250 crossflow. It had some problems and I found a freshly built 250 crossflow on marketplace. Unfortunately and sadly there was not much information given when purchasing as I acquired this from the partner of a diseaced husband. This new block is in the car now and is running. Just needs a few final parts and upgrades before it's on the road. I just need help deciphering the block codes as information seems to be difficult to find.

Codes imprinted:

JG41UT34178C
76DA-6015-CA

Hope someone can help? Let me know if anything further is needed.

Pics don't open but in US the 76DA might indicate 1976 production.

I believe the 76 Crossflow came with the iron head, not the alloy one. The intake and exhaust manifolds for the alloy head will not bolt onto an iron head.
The alloy head will fit on the 76 block.
