This is out of my realm, 14guy. This is a tuner's question. I'm just a parts replacer/tune up guy. Might be good for top end use, but the idea of the power stroke is to keep it closed to its diminishing return. Open it too soon, you lost the grunt.

Seems like a quick in, quick out speed on the higher rpm range use. I could be wrong.

The old senior moment was not thinking of the embossed cam sensor pickup on the exhaust bump stick. Something like heating up the cam to weld a sweep bump on the cam's shaft, then reheat treat it? Pre FI you could get away with it. Today? Might try custom cams already with the sensor bump cast into it.
