110lsa, off the shelf cam, dual plane manifold......2400rpm between peaks.
Would need to know the whole combo to understand this one because I have seen in certain situations a really large spread and lower than expected peaks points to one piece of the puzzle being really out of wack effectively hamstringing peak torque/hp production.

Imo, there’s no magic in the lsa. It’s about the whole combo.
