Maybe play with the DynoSim
and see whether a camshaft with
somewhat less intake duration
but more lift
results in even more torque
at lower useable highway rpm?

I think I like this cam. That midrange power is going to be very nice indeed.

After reading your other post with the extensive dyno data tables,
I too wonder if you really had valve float,
or maybe were seeing the “dark side”
of where tuned port intake manifolds resonance does not help boost air charge pressure,
but instead reduces it.

The 130 degree dyno room temperature,
and 104 to 107 degree intake air
is unusual.

The speed of sound in air changes with temperature,
so air pulsation resonance does too.

where da b00st snail(s)

You're not the first to ask. It seems a lot of people were disappointed this time.

Tiny cam, moderate compression... needs boost snail :P

What is the ideal spring to match
engine design
and intended vehicle duty?

Very important and worthwhile subject.

Wisdom of Moparts might guide to an answer.
