Is there anyone here that can positively identify a motor by it case stamp number? I've got a chevy sb 350 with the stamp number of 10066036 which is made in mexico as a Target Master/Goodwrench crate motor from a vehicle unknown. I need to know what year this engin may be from. What I can tell you to help you narrow it down: it is a 4 bolt main, and has the oil dipstick tube on the drivers side and the passenger side. I've looked up the number and it said that it was made in 1994, and i talk to another guy and he said since the oil dipstick is on the drivers side that it is prior to 1979. So I am stumped. The article also said that it has a 2 piece rear seal. If there is anyone with the knowledge I would greatly appreciate it so I can start finding the correct applications to try and get it running. Greatly appreciated.

 

there's a website..i'll see if i can find it...

 

did u ever find that website? haha im looking for the same i was told i had a sb 400 put in mine and i wanna run it and see

 

According to MorTec...
10066036...350...........2 or 4...Target Master/Goodwrench crate motor, 2-piece rear
seal, "Hecho en Mexico"

It is basically just a replacement motor and didn't come in a particular vehicle.
