    Searching parts and found this good link on V8 motors.

    http://www.avto-ultra.com/en/go/V8/tech.glossary.details.html

    The person who wrote that, if I understand correctly, explain that motors with heavy counterweights on the crankshaft will prevent the car from accelerating rapidely (as we have some large onto it)... Maybe it's why the V8 SHO is similar in performance as the V6. (?) At least, our motor isn't completely forgotten or reminded for his cams problem...

    "V8 are common in purpose-designed engines for racing cars. They usually have flat-plane crankshafts, since a crossplane crankshaft results in uneven firing into the exhaust manifolds which interferes with engine tuning, and the heavy crankshaft counterweights prevent the engine from accelerating rapidly."

    I gone to shopping center yesterday with my SHO. A meeting of sport and old cars owners took place in the parking (they come there at each week). I started a discussion with an old owner of a 2003 Mercury Marauder and he told me something interesting when I said that I have a Gen 3 SHO...

    He told me that back in 1995-1996, Ford wanted to go in Nascar race with the Taurus SHO but this race accept only cars with V8 motors. Ford then developped a V8 for this purpose (adding 2 cylinders to the V6 2.5L duratech).

    Is someone here can confirm that, maybe a veteran ? Thanks.

    In 1995 Ford raced a Thunderbird in NASCAR with a 358 Ford Racing V8. I don't ever remember an SHO but I'm getting old. lol

    Well its only a SHO on the street. The engine / tranny they use is nothing the same. They are limited to 15" hubs, so the brakes would be totally different. I'd have to check on rather the stock car actually had to have a V8, but I know the Taurus was the Ford NASCAR car until it was replaced with the Fusion.

    This does not conform with the history of the development of the engine that I have in the past read from Ford and other confirmed sources. But its all ages ago, so I do not remember details. Some of it will be scattered about on V8SHO.com, but other bits are in letters and emails from back in the mid to late '90s. I doubt I still have them, but will look about and post back if I find anything.

    +1 on Stephen's recollection. I'd read that Ford had planned a mid-engine model (coupe?) but scrapped the idea, only after a PO for thousands of 3.4 v8s had been submitted for Yamaha to assembly, or something like that. It also seems unlikely that Ford would be able to develop the Gen 3 for 1996 after being denied use of the v6 during the 95-96 race season. Surely, they already had R & D well underway. BullGeek (Nick) is also a good source for this info.

    Yes. Its pretty normal for development on a motor to be a several year project, even if it is a modification of a previously existing one. Its the cascade problem, where when you change one thing, it leads to others that must be changed also as a result. I have read that the decision to develop the 3.4l V8 was made in '92 and work started on it the following year.

    NASCAR is a joke. Those cars aren't even close to stock like they used to be. They use 355 ci(?) carbureted V8s. For years there weren't even any V8s available in the cars they were racing. Fun to watch, but its not stock car racing. That said, I can see Ford wanting to homologate a 4.0 V8 for IRL racing, like Olds did with the Aurora and their 4.0 N*, but not necessary for NASCAR. Since a 3.0 v6 with 2 more cylinders adds up to 4.0, perhaps that's what they were going for. We may never know, but it doesn't make the cars any less fun.

    Agree. NASCAR has not actually been stock car racing for a very long time now.

    Wiki-Wrong-Oh strikes again. Wiki is good for a very general look up, but horrid on details on most anything I actually know something about. I pretty much never use it for a source any more.

    Basically, because 2 engines use the same bore and stroke does not mean they are related. That is pretty much like saying I am related to all the people from the home nations of my parents that are 145 lbs and 6"2". It would be interesting, but I suspect that to be wrong.

    Just want to make a note that NASCAR has never been about "stock" components. Only that it represents a car that resembles something off-the-shelf, it's a rule that the car has have be from the manufacturer. They have too many limitations to even allow most stock cars that we see there. So when you see the Impala, Fusion, or others on the NASCAR track be assured that they only resemble the cars. Racing in any form is about testing the next generation of ideas. That is where the big money comes from, but also the regulations IE) Politics... Agree or disagree so much of racing is about testing out the engineering ideas. There are other aspects, but when you look under the hood you start get the an idea, especially when you see the hybrids and now all electric racers...

    I don't like only left turns... So I don't usually follow the racing, just the tech.

    I have to agree about the left hand turn thing. I much prefer road racing.

    A guy in my area is selling these. I never saw how the these Taurus look like before. This is realistic (promo on them) ?

    I am sure it's modeled after some version of the NASCAR ran Gen3 Taurus. Noticed the extend front for better aerodynamics and cooling, and the rear fin. Looking at Google Images of the NASCAR Taurus you will see there are variations depending on the year and team.
