Chevy motor casting and suffix # s - The 1947 - Present Chevrolet & GMC Truck Message Board Network

lt704 · 04-21-2017, 09:02 PM

Hi folks, I have a question concerning my chevy engine. it is a 350 and not the original engine. The engine casting # in the rear of the engine is 14010207 which when i looked it up is a chevy 350 engine from the years 1980 to 1985. I also looked on the front of the engine pad behind the alternator for the stamped code. The pad is not easily readable but i did find the following that i could read. It was V1018?RT I think the ? # is an A or P, not sure. I looked up this suffix code, the last three #'s and could find the the vehicle that the engine was from. The only thing close was a two letter code RT which was a 64 corvette engine. Any help would be greatly appreciate. The heads casting # is 14079261 which says it is heads from a 1982 to 1985 chevy engine, so i am guessing this engine is between a 1982 to 1985 engine??? Also where on the back of the engine can i find the stamp showing the date of the engine?

Thanks for all your help.

Check near the oil filter housing for the date.

A pencil rubbing will bring out more of the stamping than you think. If you have access to the area

There may be RPO codes on the bellhousing area too. 3 digits. On the driver side.

I bet the dipstick is on the passenger side.

Hi Gary, Yes the dipstick is on the passenger side. Does that mean with the engine and head casting numbers i have that i am correct that this engine is from 1982-to 1985 ? Thanks

GM used those letter codes multiple times over the years. Don't depend on those to be absolute. Your best bet is to use the numbers cast into the block. Your 14010207 shows to be an 80-85 350 using this site http://www.castingnumbers.info/site/...Small_Block_V8. It has shown to be very reliable.

There are a few sites with some good info to help determine what you have. There is one that identifies individual parts like heads, manifolds, cranks, etc.
