so one of those cams intended for low comp actually has low vac? I never would of guessed & I woulda thought just the opposite.


You're surprised a cam that specs out as 232/245-107(as per the Hughes site)would have low vacuum?

I would absolutely expect low vac out of that cam...... Especially in a low cr motor.

It's designed to idle rough...... Which is done by dirtying up the idle with lots of overlap.
