Re: clean 7.3 Quigley Ambo
This is a non-turbo 7.3L indirect injection engine. I had a 1994 model year E-350 with the same engine. Ford did not put the 7.3L "Powerstroke" engine in a van until the 1995 model year, and never put the indirect injection turbo in the van ever like they did for about 1/2 year or so in the pickups. I can't speak for 1993, but the 1994 model had 180 or 185 HP and 385 lb-ft of torque. There were also high-altitude versions that knocked power down to about 160 and torque down accordingly.
These are good engines as long as the supplemental coolant additive was added. Since the 7.3L IDI had high compression like the 6.9L, but thinner cylinder walls, they suffered from cavitation that caused pitting from the cooling passage to the combustion chamber. Coolant additives caused a protective film that prevented this.
They are very simple; outside of the glow plugs, there are maybe three sensor wires coming off the engine.
The engines really wake up with an aftermarket turbo, but those are hard to find these days, especially for the vans.
The E4OD transmission does not hold up well behind these engines. I went through a transmission every 100,000 miles like clockwork.
