Get Stuffed

Case stuffer™ is designed for all G23 (angle plug) engines.

Easy to install - split crank case & install around crank. 

Our stuffer is made from billet aluminum, it's milled directional for fuel/air flow. Designed to fill all the places you don't need fuel/air to be.

Stuffing the crankcase is age old modified motor builders secret. It relates to the trues horsepower equaiton as the crankcase pressure and crankcase volume quotient. 

In the old days it was usually done with a devcon type material (epoxy base) that was poured in & then grounded out. It is almost impossible to get true or even using the old method.

The Case Stuffer solves ALL this
