To quench or no quench

If by long expansion ratio, you mean the "power-stroke" or I like to call it extraction duration,then;
yeah after the intake and exhaust durations are selected and
the LSA is set,
then you have a fixed number of degrees left to split between compression and power-extraction.
And it always surprises me to see a streeter sacrifice extraction for compression, when the cure is just to increase the Scr, and give up the compression degrees instead.
I mean you can get away with that, often have to, at the racetrack, but on the street once you get to a certain size cam, it just sux gas big time, on account of all the energy that goes right down the exhaust pipes. That is why I pulled the 292 cam very early on. I hadn't thought that the price of gas was about to skyrocket.
And the more I advanced it, to get the pressure, the more energy came out the back. When I noticed that (I was still learning) I even tried that cam straight up and retarded. WTH, I had 11.3 Scr to play with,lol. For me it was just the wrong choice.
It was however, a pleasure to listen to. If I couldda bagged the sound, I might made a million bucks.
