Swap the 3.0 Vulcan for the 3.0 Yamaha?
What are the possibilities of putting the Yamaha 3.0 V-6 in place of my Vulcan? I know the engines seem to be vastly different, but from what I understand they are closely related. I know they have the same computer for a fact as they are from the same generation of cars. Maybe Rockledge can shed some light on this since I noticed his sig includes a 94 SHO.

AFAIK, and take this with a grain of salt, the Vulcan and the Yamaha have the same bellhousing. I've heard that the SHO 3.0l swap is best done on a 3.0l equipped truck for that reason, but of course I've never confirmed this. It would be an interesting swap, that Yamaha 3.0l was a great engine.

Its been done once or twice, but its a lot of work. The SHO motor takes an Aerostar bellhousing, as I recall, to work in the Ranger. (Not sure if that's the same as the 3.0 Vulcan or not...) The SHO motor is very wide, so its a challenge from that standpoint. It also likes to rev - its not huge on torque, but it will run 8k rpm, so it needs to be geared a lot different from a regular Ranger motor.
The SHO motor is a thing of beauty, but parts are expensive, so make sure your wallet is healthy if you decide to tackle this one. I'm about to do the 100k maintanence on my SHO, and a new waterpump was $125.00 ($250.00 from Ford...) and some of the parts are starting to be really hard to get.

I'm semi familiar with the SHO's. An ex-general manager of mine was a SHO fanatic, and knows every inch of them. Sure it'd take some rearanging to widen the engine bay enough to be comfy puting the motor in, but I cant say that its completely unreasonable. Just last week he picked up a 93 SHO manual with the 3.0 for $500 that "wasnt running". After replacig a part or two he had a running engine! Its going to be his project car for a centrifical charger system he's going to buy from shoshop.com My point is that he could probably come across another down the road and wonder if there's any MAJOR hangup that'd prevent such a swap.

Ok enlighten me, I'm not too familiar with SHO engines at all.
Rockledge said the 3.0L/3.2L SHO is all Yamaha, then the 3.0L/3.2L Yamaha block shares the same dimensions with the Vulcan block.
But in a previous post it was said it's much wider and hard to fit into the Ranger without modification.
So what's the difference? Is it wider, and if so how much? I'm assuming the 8K revving SHO is OHC...I can't imagine revving any OHV engine to 8K.

Here are a couple of other photos that help give you an idea of how wide the engine is:
Those big valves angle outward, and have big covers over them, and (since its dohc) its got 2 camshafts on each head. Its got dual intake runners with butterflys on the highspeed runners that open at around 4400 rpm. It has a torque curve that's almost flat to the redline, so its a blast to drive!
IIRC, its as wide as the 4.6 modular motor.

Ah I see...DOHC and four valves a cylinder...quite nice indeed.
Ok...HP and torque specs please? Looks like a monster engine in a small displacement. Tell you what though, lookin' at rubydist's second picture I think working on it would be a total PITA.

Yeah, engine out just to do plugs. That head design has always been a killer, especially with 4 valves per. Formula one race cars have amazingly small displacement but the have enormous #'s. DOHC eliminates rocker arms and behave themselves better at high revs.

Wouldn't it make more sense to swap in a 4.0 sohc as it's made for a ranger, has better lowend torque and simlar hp numbers? It may not rev to 8000, but it doesn't need to. The yamaha v8 got a bad rap for not being as fast as the v6, but I bet if they would have but a manual tranny behind the v8, it may have been a different story.
