What is your take on:

I have found the Chevrolet V8 small block mechanical tappet camshaft part number 3849346 (sometimes referred to as a "30 30 DUNTOV" because the GM factory says the lash is set at .030 thousands) runs MUCH BETTER at about .045 thousands lash.
It's from a Harvey Crane page that talks about doing a lash loop.

It would seem to me that the size of the engine might well have an affect on how well this excess lash works, but there may be more to it than just that.

The 30/30 cam doesn't have a ton of lift to give away, but it can spare the duration, I suppose- but there again the displacement would have to come into play. What might be the hot set-up on a 283 wouldn't necessarily be what you'd want on a 327-and-up engine.
