Hughes cams

Most off-the-shelf flat tappet camshafts are optimized for the SBC.

The Chrysler .904" lifter bore has about 15% more surface area than a SBC engine's .845". This allows for a comparatively higher rate of lift without reliability issues.

On the flipside of this when using a hydraulic tappet more isn't always better. At some point adding "more" cam will reduce your RPM range due to lifter pump-up. more duration will cause it to occur earlier.

So in that sense, IMO a high rate of lift is most useful with mild camshafts which are not pushing the threshold of having lifter pump-up occur while the engine is still making power.
