the best power gain your going to get is from a good exhaust, after that a good cam, and piston (11:1 pump gas, or 12:1 for extra 1.5 hp and run race gas, clean up the ports.

When you say "best" do you mean reliability, money, power??? Best means different things to different people.

When you say "drop-in engine kit" do you mean just a cam or do you mean cam, piston, crank/rod etc?

If you can clarify those two things for me, I can tell you what my experience says.

yes, you would have to ship it to me, or if you wanted to save a little money on labor, you could buy the stuff for the bottom end from me and assemble the bottom end yourself and send me your jug and head to bore/port/valves/valve job etc.

Drop-in upgrade:

11:1 100mm piston
Hone for new rings
Stage 1 hotcam
gaskets
I agree with maddog! That list he just put up is going to be your best bang-for-the-buck upgrade and will more than likely be all the power you need. You can get a raptor to almost 50hp without even breaking into the engine.
