The intended purpose of this combo is to be a reliable street car that will provide a ton of fun doing short blasts while powershifting, doing rolling burnouts, and generally causing a ruckus. It is not intended to be a max effort world-beater. That’s why I chose the dual plane intake, the 3.91 rear, and probably why Jones gave the specs he did and not some wild *** .700 lift 300 duration cam. I do still think his recommendation was light on lift but I may have failed to tell him the heads are the long-valve version and installed spring height will be in the 1.9-2.0 range.
