That's Brian's dad, Fred, on the right. He's the other half of IMM Engines. Yup, it's just a two-man shop.The intake manifold didn't fit the milled heads, so Hafliger had to machine 0.060 inch fro Finally, Hafliger had to install shorter-than-stock pushrods.

Hafliger went up four jet sizes, front and rear, resulting in a 12.5:1 ratio throughout the powerband.With air/fuel ratios mostly in the mid-13 range, the engine also wanted more fuel. Haflige Hafliger initially set the advance to a conservative 32 degrees. After a few short pulls, he decided the engine wanted more and cranked in 34 degrees.Hafliger initially set the advance to a conservative 32 degrees.
