Re: motor number
The CMJ is the suffix code. See I here.
http://nastyz28.com/gm-chevy-codes/c...s-suffix-2.php It shows it could be a 74 350 or 80 305. It’s not a 305 because your casting number 3970010 is a 350. See here. https://www.mortec.com/castnum.htm The 16D494527 shows the last six numbers of the vin of vehicle the motor originally came in. Those numbers are 494527. |
