[Walrus]

Below are the dynamometer run figures for a 495 cu. in. engine built on a Shelby 427 aluminum block, headers and pipes in place, by Kinetic Racing Engines in Westland MI for my Kirkham KMP 293.

I’d requested a tractable state of tune for the engine since there is no intent that it would be used as a flat out racer. In keeping with that, Kinetic used hydraulic lifters and an Edelbrock dual plane manifold.

I really don’t have much experience with this type of engine and was wondering if I could get some feedback from other members of this forum as to how this test shapes up against other engines.
