one sweet motor

The only reason i gave 4 stars is because we had problems with the motor being back ordered, the push rods were weak, and the exhaust valve rotators were not deleted. we ran across those problems when one of the plugs in the head for the water temp switch was stuck and we took the head to a well known machine shop and they started asking questions and said those things need upgraded. once we had that all sorted out, we got the motor started and broken in and started driving it. we have 1000 miles on it now and it makes our 88 GMC k3500 scoot! Great crate motor except for a few little things mentioned above. ...read more
