I ended up buying my own chip programmer last spring and really getting the van running great. This thing has ran great and been super reliable all year so what should I do? Tear it apart and make it better, of course!
I took a 98 350 Vortec and an extra fresh set of Summit Vortec heads on trade this summer so I'm going to freshen it up and drop it in over the winter. The motor came out of a Z71 truck and the guy said it ran great except for some lifter noise. I pulled it apart and I guess the guy didn't believe in oil changes. the amount of goo is unbelievable but the cylinders have almost no wear; you can still visibly see all the factory hone marks. Should be a nice upgrade from the 307.
