I have one of these engines, with Jakes (which I've never driven) and was wondering if this engine is a good candidate for my daughter's B61 project. The truck has a double over tri-plex trans with a 4.25 rear, on 22 inch rubber. I would like input from persons with experience both from the driver's seat, and maintenance personell, with this series of engine. It is a two valve head edition, and is a 1982 model year from a WS series Mack. It does run well, (on a stand) but I have not actually driven it. I'm looking for good, usable, and unbiased input before I "freshen" this motor up prior to installation into the chassis. Please include any pros, and cons, to the issue. Thanks for your time. Regards; Rob Swallows
