Engine repair / upgrade after road trip
Somewhere between the Grand Tetons and Yellowstone, approximately 1000 miles into our 3400 mile road trip with the camper, the Ford 7.3 decided to run on 7 cylinders. I had gambled a bad fuel injector...

Not sure if I mentioned this in my previous messages but the Estimate Peter gave for HP figures was 450 at the crank. Obviously it is a guestimate but I trust his numbers as he used to race 7.3s at the track in his earlier days when he had a heavily modded 7.3 Excursion. Would be interesting to put it on a dyno someday but I'm in no hurry.
What I will say from just the little bit of driving is that I've honestly not even floored it yet and it's been scary fast. Putting the pedal down just 2/3rds of the way pushes you back into the seat hard. Since it redlines at 3000 rpm and idles at 900 rpm, there is really just 2000rpm to work with between each gear shift. 1st gear is pretty much useless as it will just smoke rubber, 2nd gear goes by very quik and 3rd gear is where the most fun is as it starts pulling HARD. Passing won't be a problem any longer.
I've not driven it with the camper on the truck yet. That will come this weekend once I pick it up from my friends place who let me store it there. Rest assured, there won't be any full throttle sends with the camper of course. I am looking forward to the next trip in the mountains to see how the EGTs hold up. That will be the ultimate test that matters for me. Before these mods I really wasn't lacking for power but the EGTs where always high so I could only go about half throttle on a steep grade when pulling the camper and trailer together.
