I always drove my Healeys like IMO how they were built to be driven. Hard, fast & fun,not abused- just driven, not [censored] footed around.If a brg is suitable for 'street' only, I would not install it in one my engines.I've built engines that went right on the dyno & ran 50 runs(turbo engines).never heard of street 'only' brgs. Just my thoughts.
