A Stage 3 engine kit for the hemi-head Predator 212 (model 60363) that adds a racing cam, a 22mm Mikuni-style carb, an aluminum flywheel and a billet rod. The seller claims 13-15+ hp, a big jump over a stock engine and a step past a Stage 2 kit. It suits kart, mini-bike and small-engine builders who already know their way around a 212. It only fits hemi Predators with the cast aluminum valve cover, not the non-hemi 69730. Peak power still depends on porting or milling the head, which the kit does not include.

This Stage 3 hop up kit is for 212 Hemi Predator engines. It is a step up from the Stage 2 kit, adding a racing camshaft, a 22mm carburetor, and a billet rod. The kit produces 13-15+ HP.
The camshaft is a choice between a Rattlesnake cam and NR Racing's 252-0607. The 252 package comes with 26lb springs and chrome moly pushrods. The Rattlesnake package comes with 18lb springs only. For maximum power, the head should be ported and/or milled.
The air filter should be sprayed with a K&N type oil, especially for dirt applications. Oil is not included. If the optional header/exhaust is used, support it with a bracket or brace to the engine or the frame. Otherwise the pipe may fracture or break.
