The Stovebolt Site Forums The Shop Area Engine Shop Engine Casting Number

Hello Everyone,

I recently purchased a 1965 Chevy P/U. I am trying to identify the engine. The block casting number is 473483. I accidently found one posting that lists it as a 250 6 cylinder from 1975 to 1985. There is a GM and an 82 stamped below as well. How can I positively identify the year of this engine?

Thanks
Joe


PS. It seems that the engine in my 65 C10 is a 1982 4.1 straight six. The TLH means it was created in 1982. Makes me wonder if the GM and 82 stamp holds true for all after a certain date. My head number is 3962084 so that matches too.
