makya Posted May 8, 2010 Report Share Posted May 8, 2010 What is the most reliable engine that was installed in the 720 trucks...... Pre hardbody?....... Opinions or past reviews?? L20 IMO, it was tried and true. the Naps-z motors were just an attempt at smog controls. I don't remember there being a v6 in any of the 720's, but I'm really only into the older stuff, 79 and earlier. Quote Link to comment
datzenmike Posted May 8, 2010 Report Share Posted May 8, 2010 That's easy, if you think about it. The SD22 and SD25 :lol: :lol: :lol: Quote Link to comment
sick620 Posted May 8, 2010 Report Share Posted May 8, 2010 L20B fo life. IMO Best engine in the world. I have seen one pushed to 600,000 miles. And you can build em to be fairly quick. Quote Link to comment
