I'm with Jon, if she ran and you didn't hear any strange noises, then she should be ok. If you want to hear it run a lil bit, do this. I'm sure you have a spare RBV fuel tank laying around, drop a few gallons of good gas in it, wire up the fuel pump to straight power jumper wires from the battery, and just splice in the fuel lines right at the fuel filter, leave the return line where it is. Your not going to drive the donor, so you don't have to mount the fuel tank (you can even drop the donor's tank, refuel and leave it down if you really want to hear it run longer). But honestly, I say your ok at this point. You would know if you had a bent valve, pushrod, or bad connecting rod the few seconds it ran...If that trans is a 5R55E, Brandizzle would be interested in it for her Sport Trac, as her case is busted at the tcase adapter...PM me if your not gonna use it...
