Just FYI, I had OConnor Racing build my top end, and it was under $ 600.00 for everything. Gaskets, piston kit, all machine work, shipping....the works. You can find a good used carburetor for $75.00 or less with some looking. Good deals are out there on pipes, too. Bottom line is, if you get O Connor Racing or Flotek or Wildcard Racing or another local builder to do your engine, you can put together a whole package (pipe, reeds, carb, and all) for right at or slightly under $ 1,000.00.
