Cowl shake, in a uni-body Jensen-Healey? I submit anyone who thinks they are experiencing cowl shake in their J/H has never driver an Austin-Healey or TR4 or just about anything using body on frame construction. Personally I've never experienced cowl shake in either my J/H or TR7 both uni-body cars, my Austin-Healey though is another matter.
I agree that the body on frame AH is loosey goosey due to its construction. While the JH is unibody and therefore much more rigid, the absence of a steel roof does compromise its structural integrity compared to a unibody coupe.
I do believe however that the steel plate behind the center stack is necessary for the best possible outcome. The TR6 used the same method in the form of an aluminum casting bolted between the cowl and the floor.
And yes, compared to the older body on frame method ala AH, the JH acts like it is carved out of a solid block of steel. This does not mean that it cannot be compromised, and I was merely suggesting a place to look should one find unexpected cowl shake in their ride. But I bet you knew that, yes?
