[Healeys] Fast Flow Inlet Manifold

[Rick Swain]

Does anyone have any experience with the "Fast Flow Inlet Manifold" listed as
a new product by Moss Motors? I believe it's the manifold that Rawles
Motorsport in the UK says they developed. I've always thought the stock
manifold looked pretty inefficient. The Moss site suggests this manifold
performs best with 2" HD8 carbs and a six branch exhaust header but that it
can be used with 1 3/4" carbs and the stock cast exhaust manifold. Since I
have freshly rebuilt HD6s and a basically stock 100 Six engine (except for a
BJ8 cam grind), I'm interested in the latter route. Comments or suggestions?
Thanks
