Topic: Who’s still using a 7.3 diesel truck

Posted By: jimh406 on 02/21/21 04:10am

36guy, sounds like you couldn’t drive a manual shift, didn’t do proper maintenance including oil changes, and modified ito use non OEM parts and it’s Ford’s fault. [emoticon] At leat, you found something you liked. [emoticon] That’s really all that matters.

Wow, I've read some kooky posts and ideas on here, but I think this one takes the cake.

Two years ago I bought my dad's 2000 F250 7.3 Supercab with the 6 speed manual. I helped him spec it when he bought it. I don't daily drive it, and to be honest I haven't done anything with it yet that any 1/2 ton truck could easily do. When I retire in a couple of years I'm going to get a 26-28' travel trailer and install a Rampage lift to haul my Harley. Some of the mods I'm considering are:

Convert axles to 4.30 gear ratios
Install Gear Vendors overdrive. This will give me twelve possible gears, with roughly the same overall final drive ratio for cruising on the flat while giving me lower gearing for low speed backing, etc. The stock reverse gear in the 6 speed is pretty tall.
Towing chip or tune, aiming for about 300 hp/600 ft./lbs. Nothing too crazy.
South Bend towing clutch or equivalent when the OEM clutch finally wears out.

It's a strong, dependable truck, but my dad's new F350 with the 6.7 towing 10000 lbs would probably out-accelerate mine empty.

Where’d you get that little tidbit from???

That’s not even close to true. It always amazes me when I run across a new urban legend. It makes me feel like I’m missing out on something [emoticon]

It is funny how some actuall owners feel offended with the true facts.
As I pointed before -7.3 has bulletproof block, but on 20 years old trucks, orings, reservoirs and sensors will fail, so if you still own 1 - read the forum replies and put some preventive maintenance on it, or YOU WILL get strangled.
Final note, when things are relatively easy to fix on 7.3, stupid oil cooler replacement on 6-leaker can exceed older truck value.
Than my 6.7l develop oil pan gasket leak on 2nd year. Suppose stupid gasket replacement require engine pulling. Covered by warranty, so I did not get the bill, but my "new" 1922 Ford Model T doesn't have leaky gasket, so how come 100 years later Ford is still struggling with basic stuff?

I gather you love your old Powerstroke and that’s cool. They are awesome trucks, but this is, one of the funniest, most ill-informed statements I’ve seen on this forum in a while!

Edit guess I was slow on the draw sorry for the repeat

How come you complain and bitsch and are always 100% antagonistic?
So you’re saying your new model T is running an original, never opened up engine that not only runs but doesn’t leak?
Aside from not believing that, if it was true, it’s a miracle.

Sounds more like a lemon to me. It happens with all vehicles.
I don’t get the impression that the OP didn’t take care of it. Idk about the input shaft issues though. Not familiar with those trans.
I do know the 7.3s were a cold blooded engine that needed properly operating glow plugs and that good oil change maintenance was imperative on them (and 6.0s) because the HPOPs were good but finicky without frequent quality oil changes.

Every vehicle has its quirks. But there’s quirks and there’s issues and they had quirks, not issues.

I’ve got a Gear Vendors OD. It’s awesome but it won’t give you twelve gears.
You have to be going almost 20 mph to use it, so it’s oil pump is operating.
You only use it with the upper gears.
I have 4.10 gears and the GV drops my 60 MPH cruise from 2000 RPM down to 1500.
It makes 4.10 effectively 3.20.
