Another timing curve question

I'd leave the PVCRs until you've hit drag strip (or dyno). Then if the jetting for best mph is different than best interstate cruising, change the PVCRs.

Be interested to know how big the primary idle restrictions are.

I spent the late afternoon modifying a 1" combo wrench to better fit Holley inlets. Something that I've been meaning to do for a long time.
