Amazing what the brain can forget. The Yamaha built 3.0 V6 that came in the Taurus SHO was absolute crap. Yep, for the time it made a lot of power, but it didn't last long. The engine was prone to timing issues with the cams. It was an interference engine. Most commonly the engine cratered long before the 12 month/ 12,000 mile warranty expired. Ford took a huge beating on this engine. Remarkably, the timing system on the Yamaha 3.0 is identical to the one on the Dodge 4.7. Dodge hasn't had the problems with theirs but designer of both, General Dynamics, warned the Chrysler group that the timing system was prone to failures due to the experiences with the Yamaha engine.
It looks like an expensive thing to construct, although you do get OK overall size from V6s (and balance problems).
I wonder how one of those engines compares to a modern aluminum LSx in terms of HP/lb and fuel consumption.

Knew several people that had good luck with them and made well over 100k with no major issues. Perhaps the people that drove them like Days of Thunder and didn't maintain them had issues?
Spousal Unit bought a used Taurus SHO with allegedly 80K miles on it back in his grad school days. It was dead in our driveway before we finished paying the loan off, largely because of engine issues.
That experience put me firmly on the 'only buy new because then you know exactly where it's been' camp.

C'est la vie.
I can't think of much of anything post 1971 that's worth rebuilding (Turbo Regal maybe?).
there you go, the festiva shogun. I could swear it was used in the ford escort, merkur xr4ti, in very limited numbers???
anyway, the sho in a festiva is like putting a v6 vtec in a civic, vr6 in a gti, with a good tune and turbo, forgetaboutit!
Nope Escort GT and EXP, Mercur XR4Ti used a 2.3(turbo for Mercur). Escort never had a v6. The V6 was midmounted in the Festiva, the idea was based on a particular Renault that was converted to midengine and used in WRC, group B I think.
The Festiva SHOgun was never a production car. Only 7 were built. There was also one, officially, built SHO Ranger, built by Jack Rousch.
They also sold bodykits, and many people have made SHOgun clones. The wheels and supertrapp mufflers ehere easy to get. they weren't super great, but they better than in the Taurus as far as performance.

Escort and EXP had the 1.6ltr up to 85. GT was turbo charged IIRC. Then it was upgraded to a 2.0. The EXP never saw the 2.0. The XR4Ti was a 2.3ltr turbocharged engine. The "Escort EXP" used a 2.0 engine

I recall the v8 SHO having some cam issues where they had to be welded. I know because I owned a 97 SHO with the v8.
The V6 yamaha's were pretty bulletproof if you ask me. I know because I owned 3 of them all with over 100k miles and no engine issues whatsoever.

The 3.0 and 3.2 were virtually bullet-proof as long as you performed proper preventative maintenance on them. It was the 3.4 V8 in the 3rd-gen SHO that had the timing issues. The cams were sleeved onto the sprockets without adequate reinforcement, so sometimes the sprocket would out-spin the camshaft under heavy load and that's when you had serious timing issues and possibly destroyed valves and pistons. It was a major problem when it happened but there was a simple preventative fix using a roll pin to reinforce the sprocket/cam sleeve joint.
