Hey Nick, there is a stealer over here in Nashville that has advertised the same conversion that ERHugger had done for $900 total (I'm sure plus sales tax, and you know how THAT is in TN). Give Smokey Mountain HD a call. They usually have some pretty good winter specials similar to the dealers here in Nashville.
Call Head Quarters or look them up on the internetthey make excactly what you are looking for, I did mine 2 years ago makes 85 HP at the rear wheel; no cam change, just bored to 1200 and good head work.
Cost me around $1800 if i remember right.
