If you are mechanical and read some of the how toos on the web its a snap. Id recomend while you have the intake off to swap the cams for some decent PI sticks. If you look around you can find them used for hella cheap(I bought mine a year ago for 30 bucks on Ebay). That combo will yeild the best bang for buck. Prolly 20hp or so. You can find good info on cam swaps too. Just dont take the front cover off, use C clamps or "the tool" to hold the gears while you swap the cams. Saves alot of time.
