Questions: I have several L134 blocks. some have parts on them but one is bare. How can I tell if it is a chain or gear type?
Question By: Scott on Aug 14 2018 9:54 PM
The front timing is where you can tell. If its gear to gear or chain. Or you can look at the oil pump if its there and see the orientation of the gear.

Questions: I have two L-134 engines. One is a new casting. One crank shaft has the bolt on counter weights and the other is completely cast. What are the difference between the two and are they interchangeable?
Question By: Kyle Thomas on Feb 9 2018 6:25 PM
They will interchange with each other. Just double check your dowel pins to the flywheel to make sure it matches there.
