Well, they actually slotted me for one that is going to get here a little quicker, so I am now SPF 2813 and Superformance .

You are lucky to get quicker delivery!!! Although worth the wait it can be painfull, LOL!!! I have the 427sr/tw with 600 and cruise all day long between 1600 and 2400 rpm and it is as smooth as it can be, in fact I just got back home. Everyone warned the 427R may be a little lumpy at idle, the 427SR/TW is plenty lumpy enough to scare everyone away but not enough to wear you out. Roush says nothing greater than 3500 rpms for the first 1K and Centerforce says no full engine torque for 500 miles. You only get to break them in once you might as well do it right.
