My first 7.3L was an early '99. It has been the truck all of my others have been compared to. That truck ran VERY well with some pretty heavy loads. I sold it with 270k on it after buying it at 132kish.
I don't know that there will be any real hot rodding of this truck. I want to tow two Jeeps, a Jeep and a Buick, two Buicks, etc with it. I would bet it'll be fine with the intake that's on it and maybe a performance exhaust? My early '99 had the Edge with Attitude and it towed very well with those mild mods. That would be extent of the manual truck being hot rodded. (at least to me). I want reliable and to top summits at about 65-70 mph with those heavy loads. I'm even fine if it's 62 mph or so on the summit's
mbryson F*rd truck history
-'99 F250 CCSB auto
-'01 Excursion auto, (maybe put 10k on that one) ---super nice XLT that I had just put a fresh trans in. Hated the suspension but kind of a cool wagon. Sold the F250 and Excursion on the same day with people traveling from far away to get both.
-'96 F250 ext cab long bed auto (20k miles on that one) ---clapped out old dawg I used as a yard truck. Killed by kid drivers
-early '99 V10 CCSB ---lifted WAY too high but a solid old dawg. Put about 35-40k on that truck. Had a fuel pump go bad. Nothing to complain about at all.
-'01 F350 CCLB, auto (bought cheap with fresh trans and significant body damage--- Lariat with the interior that was coming apart. Needed injectors and glow plugs. Sold for double what I had in it (maybe should have kept it?). Put about 15k on that truck)
-'10 F350 CCSB V10, known as "Sweaty Betty". Put about 50k+ on that truck. AWESOME truck... tough call if I liked this truck or the early '99 more. Early '99 could pull a little better but the V10 didn't suck to tow with other than using gasoline. Bonus points on that truck is that it's dirt simple. No injector issues, turbo, injector pump, etc. Just feed her gas and use the skinny pedal. Betty will give you what she has even though she has a drinking problem.
-current early '99 F350 CCLB manual, .... 100 miles on it by me? bought with 301k. Time will tell about the manual.
I am still VERY tempted by the '05-07 6.0L trucks but just don't want to deal those dawgs. I'm NOT interested AT ALL in the 6.4L trucks unless there's an equivalent year Cummins swapped into them (and I don't know the Cummins issues well either). That leaves me with 7.3L SuperDuty, V10 from 2005 up, 6.2L 6 speed auto and I'd probably roll the dice if I could buy a warranty on a 6.7L deezel. I'm a bit of a cheap bastard as all of you know and this '99 will likely serve my needs for many years at 4-8k miles per year? We'll see how it goes
