Beyond dropping it on the block, I think the chains are different (double row), exhaust, induction, wiring, different front cover, different crank gear, different ignition system, and so on. But, I'm no expert here. Having seen both engines, they sure look a lot different. What are you thinking about trying to accomplish beyond the obvious performance boost. (not sure the increase is worth all the trouble and $$$). MAybe Steve or Donnie can help..
