To JB Vobra, I believe you when you say break-in makes a difference. I just got my dream car yesterday (Bullitt #5290) I would like to know in detail how to properly beak in this modular 4.6. I've heard too many controvercies. You seem to know what you are talking about. Thanks. Dave, Ford Motor Company Employee.

well Dave, the only real thing to be concerned with the first 1000 miles or so, is don't go take a 4 hour highway trip with a brand new car. You want to vary the rpms quite often to let all the compenents "seat/settle" properly. Basically, keep your break-in period around the city and do alot of start/stop driving. Avoid long 70mph cruises at the same rpm.
Other than that, I'd change the factory oil around 1000 miles. Probably not a good idea to leave the original oil in any longer than that. Who knows what particles get in the engine during the assemlby process.
As far as limiting rpms or such? I'd say hogwash to that. I've been all over this car since day one. At least 4 redline shifts every day I've driven it (responsibly, of course :grin: ). Car has 4200 miles now and has endured 4 track trips, 4 dyno runs, and a whole lot of street cruising.
I say: "Have fun!"
