340 Initial timing questions

I think you have kinda hit on a combo that's "off the map". It runs so well, IMO because it's a solid camshaft. If it was a hydraulic with the same specs, it'd lose a lot on the bottom end. Hydraulics "act" about 10* bigger duration than a solid with the same numbers. I think that's what makes it a good matched combo. At least one of the things. This just proves what I always say.....there's more than one way to get the job done.
