Gambling on this thought process myself for the new build…hoping it pays off Won’t know for quite a few months as I just got the block and heads back and like to take my time with stuff.
If you give me your bore and stroke, compression ratio and the rpm where you want to make peak torque and I can run a math program I use. If you give me your intake valve size and I can get you close on lift.
I may be able to give you an LSA with those numbers but I have to find that math.
It would be interesting to see what my math says compared to what you are thinking as far as duration goes.
Edit: to calculate an LSA I’d also need your rod length.
