When I’m testing on the dyno, I usually prefer to find the point of valvetrain unhappiness, or run the engine as high as I feel is safe(for the sum of the parts)…..whichever is lower.
With Hyd lifters, valvetrain unhappiness usually happens first……..and I like knowing at what rpm that occurs.
Sometimes though, on a really mild build………it peaks so low, and the curve falls off so fast that you don’t find the float, or get to the safety limit.
I suppose we could've kept going. I didn't really think about it much, but now that you mention it, I'd liked to have seen where it starts to fall off. I'm used to big blocks that don't rev that far. This will be different for me.
