The crank and rod tolerances have been changed over that last 3 months to handle the power these things put out.
The MG 66 Gen 6 shares a lot of the refinements as id put these into place before they made my engine. Some of them the Go Factory included for me out of their own generosity. The MG66 however has a new sleeve design and port timing as well as a differnt crank balance. This is an exciting engine as its the first that Go Have made as a Factory Modified engine. The Modifications have come from my Research and Development over the last 12 months. The MG66 will include a Spare Rod , Rear Bearing and Carb Restricctor Kit.
Whichever engine you choose to run you will be very pleased with its performance
