Engine code help t4t?
The block in my new 1972 K10 is painted blue which makes me believe its a '73 to '81 block or whenever they switched to black paint. The numbers off the block are K1122t4t and t91518947. It's a Canadian truck so the K for St. Catherine plant makes sense. I have never seen t4t as an engine suffix before.
Any ideas what that means? |
