A highly debated topic, these 2 items are what I did after grilling my installer on more than a half-dozen occasions BEFORE choosing to get them installed (and consequently have a successful, whine free install to boot):

(1) Heat Treatment Cycles: Run your car for about 20 miles at varying speeds & rpms. Let cool down for about 2 hours (or more, can't hurt), and repeat 2 to 3 times. To be extra safe and sure of proper mating of the surfaces, I did about 4-5 heat treatment cycles. But honestly, I think that after the first 2-3 cycles, no other metallurgic changes will occur that haven't already.

(2) Take it easy on her for about 300 miles (i.e., that doesn't mean you can't go 70, 80+ MPH, or jump out in front of other cars on the freeway -- just no hard launches for a while.)

Again, I know the above has been highly debated as to whether its necessary, but my labor warranty expressly stated that both these 2 items be followed to keep a 5000 mile labor warranty valid. (I'm not entirely sure how they would know if I didn't follow these steps exactly as stated, but why tempt fate: it was in my best interest, and I figured they put them on the agreement for a reason.)

Nothing worse than trying to solve a gear installation gone bad.

BTW: The old 3.31s will tuck neatly back into the FRPP box if you choose to save them. Just beware, they will stink of rotten eggs. Kosher?

What were you guys doing at Brandon Ford anyway?
Weren't they the ones who drove luckydawg's car into the pond?

The owner's install actions are not going to keep me from using the dealer where I have purchased my last two mustangs and also had all my maintenance done for the past 4 years.

However I do remind the Service Advisors that my car has no James Bond buttons that transform it into a boat or submarine so please don't try..

LOL! I know I was just messing with ya!

Your car looks great BTW... One of the best on the forums for sure.
Especially after the Roush front and GT500 rims.
Did you do anything with the rear?

Sorry for the hijack OP.

Cooling down will take more than two hours. It takes extra time for the heat in the parts of everything above the diff fluid level to work its way out. And the oil is not being stirred to keep warmer oil flowing up against the pumpkin casting and its cover, so there's only some weak convection currents within the fluid, which I would not count on for much.

I'd let at least the first heat cycle cool down overnight.

If this sounds like I really hate to run any extra risk of having to do things over - - - it's because I really do hate to. And because I've been through having to re-do a couple of things to know.
