The inetersting thing is if the lobes spec'd were assymetric, and I'd bet they were... then it should have had MORE cylinder pressure than the 9.5... And probably more oil contamination of the chamber too.
Good point, and we both know what oil contamination means... :read2:
I still don't like the his intake mods. A great big dominator, restricted by a 4 hole spacer inset into a single plane manifold with big runners, then restricted again at the intake port entry then out to a big 2.10 valve. The cross-section would look like balloon caterpillar.
