Hi. I have a strange block. Casting number 9790071, with no engine code or VIN stamp on it. Date code D088. It has '62' heads sitting on it.
I have not been able to find anything on these codes:
- On the back next to the date code is a D->N, and below it a 10 (see pic) - what is that D->N 10 meaning?
- In the front near the frost plug there is a 'GM10'. What is that referring to
This is supposed to be a RA(III) engine, but I can't tell what I have here. Is there anyone that can explain this block with no engine or VIN codes?
In the end... I'm wondering how much to put into this block. It's in a 69 TA.
