I had no luck in the 60-66 forum so maybe this one will help. Original post is here: http://67-72chevytrucks.com/vboard/s...40#post8568840

I have a 66 c10 needing to be rebuilt. Started looking at the engine and thought I'd look up the engine size because I believe it could be a 235 or 250. Straight 6. Found out the casting number and ID number registered as a 1976 250cdi with a TH200 transmission stock. I habe a 3 speed manual.

Can anyone tell me what car or truck this engine came out of? I have an idea of year and all that but not specifically the car make or model. I think that would help when ordering parts but have no idea how to figure out those details.

371277 casting number
