I have a 92 b2600i and i am not sure if it is the original motor. My previous truck was a 2.2 and had a timing belt. This 92 2.6 has a timing chain motor.. I didnt know if it has been swapped out or not..
yep thats the original motor. It will say "12 valve" on the valve cover and be fuel injected. It has nothing in common with the F 2.2, its a different engine family (G), so nothing will interchange, not even the transmission.
