Hate to tell you but that looks like the knock sensor. Hopefully the new engine has it installed, look for a connector at the rear of the left cylinder head.

 

ok i looked up a knock sensor on rock autos website it does look like that. i am assuming that the brass side should connect to the drivers side cylinder head? thanks again for your help

 

No, it's under the intake manifold.

 

we got it running and returned to its owners so thanks again
