    it was in the 79 -82 Plymouth arrow cars and truck, dodge colts, and D-50 pickup. It is also a2.0 liter from the astron engine family like the 2.6. The G63B is a 2.0 liter from the Sirius engine family.

    My 1986 2.0L G63B is a non-interference engine. I've popped a few belts and never had an issue with valve to piston contact. The 2.6L 4G52 is another story and if you break a chain on this motor your going to have a mess on your hands, not just with the chain either, lol.
