Why with a 7.3?

Why is it that with a 7.3 it seems difficult to get the numbers that a 6.0 or other diesels have no problem? I know the 7.3 is a very reliable motor, but what makes it so difficult getting tons of power out of them?

There are a conglomeration of reasons...more efficient designs, injector differences (spool valves), higher RPM engine, etc.

Well...The HEUI is what sets it apart from the common rail/mechanical injected ones (Cummins, Duramax, and the Ford 6.4 and 6.7's, but the 6.0 is still a HEUI style injection system.

Why is it my Buddy at work has coolant puking out of his degass bottle on his 05 6.ohno??
Give and take.
7.3-Older, big, very torque-y and reliable. Against newer, more ponies and stress. That's my opinion. I love my 7.3 and it's power with just intake, 4" and DP tuned. Plenty of power and TONS of torque for towing.
The 6.0 can be great engine if you want to spend lots of money on head studs, egr's and oil coolers. Otherwise it's a ticking time bomb, IMO.

I said the 6.0 and OTHER Diesels. It was just a starting point. What about the 7.3 compared to others? Ford or not.

this is why it bugs me when someone is hard on the 7.3 bandwagon. it is puking do to him not paying attention to his engine and doing the proper procedures to prevent hg failure. or egr failure.

and i can say that cause i have had 3 7.3s. and i was glad to get rid of them. i love my 6.0 and no issues what so ever.

It's old man. It came out in the late 80's. It's a frigin tank that is reliable. Not a newer high performance diesel. Apples and oranges. Do you want to compare a late 80's , 90's Duramax or 6.ohno to a 7.3? You can't. Apples and oranges.

Cool man, I've got a 2000 F-250. Hearing someone compare it to a tank....SWEET! I'm in no way dogging the 7.3, I wouldn't have bought one otherwise. I just wanted a comparison, that's all.
