Heater hoses were not connected when I got the truck project, so I need to figure out where they are supposed to go.

That will be a fun engine in your truck. A small hole drilled in the T/stat is usually enough to get warm water up to the front of the manifold. If you don't drive the truck in 20 deg F or colder temps a 1/8" hole should work fine.

Thanks. It will be a summer ride only, so no concern about very cold temps. The engine should put out 400 ft lb of torque with a nice flat torque curve. Looking forward to getting it on the road this summer.

Do I still need to run a hose from the intake manifold to the water pump? I may not put a heater in it for the first year.

Thanks.
