Sorry to hear about your truck. I know your son hated to make that call, rode my dads bike and broke the transmission in it. Turned out to be a couple bolts came loose, not my fault but still dreaded that call. Why not do a roller cam conversion on the 355? I mean its about a $600 upgrade but then your good to go. No Zink oil additives and you can go with a more aggressive cam profile without sacrificing reliability.
