I recently purchased a sand rail with a v6 gm motor. I need to know how to find out what it is out of. the numbers 92181571 where stamped in the section below the main block and were covered up partially by a bar code sticker. Other than that I cannot see any other stamps just casting numbers

well first of all i welcome you to gmforum.com and encourage you to stick around. I am sure you will find any and all answers you may be seeking.Now as for your v6 if you have a picture you can post it would be nice.If you are not sure on how to do so i or one of the others would be happy to assist you

Welcome....and I'm sure a few pictures of the motor and rail are necessary for identification purposes.
