Questions About Buying a Modded 7.3

I found a truck locally, and am a little concerned with some things about it.

I know the truck hasn't had an easy life, it's been to the drag track a few times, but not all the time.

It's a 2000 F-350 SRW 7.3 lifted on 38s.

It's got a built trans (auto), 250 cc injectors, ARP studs, chip, and the usual mods, gauges, intake, exhaust... With a stock turbo.

The questionable parts start with it's had a bunch of parts replaced, mostly commons parts though. It's had a engine rebuilt within the last 2,000 miles or so. I was told, it was torn down for what he thought was a blown head gasket. This turned out to be a bad water pump leaking coolant, and a injector that wasn't torqued properly. This injector worked its way almost out. When they pulled it out, they couldn't find the O ring. It was later found in pieces in the # 7 cylinder. But the pistons and rods all looked good so it got reassembled.

I don't really know if the head gasket was bad or not, but I've read if it was, chances are the connecting rod for the cylinder closest to where it failed would likely have been twisted from coolant in there, and it would probably fail in a short time.

I'm just interested in hearing others opinions on this and if it would be worth buying or not.


Thanks,
Alan

engine tear down for a leaky water pump/ HG misdiagnosis? sounds fishy to me...and to not notice a loose injector during diagnosis? I dunno, sounds fishy to me. Have to be REALLY loose.....in order for the o ring to make it into the cylinder. I'd run away if it were me.

It seemed a little off to me. I was more worried about the pistons or rods being damaged. I can't imagine metal pieces in there wouldn't scratch anything. He said there was no block or head damage.

I heard it and drove in it, I'm no expert but I didn't hear any strange noises.

There is still some issues that need to be fixed, the cruise isn't working right now (He said it will be fixed before sale, by Ford dealer) And a bunch of electronic stuff, which seems to be traced to water from the windshield leaking into the fuse box.

The trans was just went through because the case had small a crack in it. This is the reason the previous buyer didn't take it. The buyer was on his way driving it home and the trans wasn't working right, which turned out to be this crack.


Edit: 250's were done very shortly before the rebuild. I know the turbo is small for the injectors, and can be blown up pretty easily.

Yeah, I never buy anything previously modded, for the fact of uncertainty. I would be concerned about #7 as well due to the metal. Who tuned it?

Matt at Gearhead. I've been told it was never turned up past econo, which I don't really believe.

I wouldnt believe that either. If you spend 2-3k on injectors 700 on studk, tunes, gauges, etc. You are going to use it, not run econo.

Yeah. He said it was to save the stock turbo, he didn't really want injectors that big, he just got a deal on them.

I was looking at it basically because it's priced right around stock trucks, and with a V3 Vegistroke, filtering setup, a bunch of oil, it seemed like it was worth looking at.

Yup, black, crew cab, long bed. He didn't send me vids, I saw them the weekend they were taken, he posted them on a local site, where we are both members.
