350 identification help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just brought home a ‘66 C10. The owner said it had a 350 installed by previous owner. I wanted to see exactly what we had. Here are the block casting number and suffix code/ partial VIN on front passenger pad.

Block casting # 3970010

Front pass. side pad info:

T0831CKH7
17D410130

I see where other people online have had this same suffix code of “CKH7” but nobody ever comes up with an answer. I see “CKH” listed on many sites but not with a 7 right behind it.

Asking the experts here to chime in and tell me what they can about my engine.

Thanks,
Michael
