Many replicas have cowl shake, some just worse than others. Some replicas don't have cowl shake at all, like an ERA.
This is not about one manufactuer vs another, it's simply an observation from myself with some considerable experience on this issue with a number of different replicas.
Consider my first replica, the Excalibur. Not only cowl shake, but it seemed like EVERYTHING would vibrate, squeak or squeal. The car was not "tight" except in it's frightfully stiff suspension. Which would induce a back ache in short order.
