Why no 351 Windsor?

What does a $100,000 specially built 600hp race engine that is built that way (5.0, pushrod, EFI) because of a specific set of rules have to do with normal street cars? A 351W will always be more capable then a 302W because of its larger deck which enables larger bore sizes and larger strokes/rods to be used for capacities in excess of 7.0 litres. The furthest you can take a 302 is 5.7 litres.

And someone correct me if I'm wrong but aren't all Ford V8 supsercar engines since the introduction of the V8 rules Wheezers?

[Perana]

Yes they are... Not much in common with road going wheezers though!

[Ghiadude]

Fords in v8sc use a motorsport block not the road car block.

[Gammaboy]

But that'd never win you a race in the pub!
351W was a pretty good truck motor anyway....

[Psycho Chicken]

Well naturally, would you spend $100,000 on an engine and use a $500 block?

[Barry_v]

its still the same block, just made stronger and the cylinder walls thicker to cope with lots of re-bores. they have big port alloy heads too. the inlet manifold is the biggie, totally different to a road car setup.

[Gammaboy]

funnily enought those heads are closer to clevo's than windsors....

[Barry_v]

yeah they are massive ports. the inlet manifolds resemble nothing road-going though, they run an offset distributer they're so big. i think they used to run the injectors outside the manifold too, do they still do that?

Yeah I know it's the same design but it's not the same jobbie you'll find in the $250 302 you get out of the Trading Post.

The Yates heads they run started life in the early eighties with canted valves, a unique exhaust port and intakes that were basically a 4V clevo with a port stuffer... I dunno exactly when the transition was made, but they now run a non canted valve geometry, unique exhaust ports and an intake thats derived from the earlier stuffed 4V type.... I think they start with the Yates head casting thats intended for Nascars running restrictor plates (smallish ports), more room for optimising the porting.

There wouldn't have been any of the teams spending $100,000 per engine in 1992/93 (unless you count staff wages).

I believe they still do. I can remember seeing a few pics of the engines with the injectors inside the inlet trumpets on top of the engine.

Well guys, I am putting a 351 Windsor into an EL, so at least there will be one on the road, finally.

[Jase]

I comtemplated it also aye.

Should bolt straigh ontot 5L mounts... the 351C's do, and i think the stud patten for the bell housing is all the same aswell.

Should be fun, loooots more torque!

Just going back to the Boss/SVT Cobra R engine comparo, the research I've done the Boss 5.4 Block is a F series truck block, where as the 5.4 in the cobra R was a limited run, they used specific casts for them which are design to only be used a certian amount of times, then throw em away. I found this looking on one of the US sites. Agree about the 351w, much stronger block standard and the bolt pattern for the auxileries and bell housing are the same. Been thinking about doing this to my EB XR8, but getting an XB coupe shortly. There goes the funds for that upgrade :

I remember reading in a US magazine that said the SVT Cobra R block was from a Lincoln Navigator which I thought was the same as the F-Trucks?

It is basically the same, the only difference I know of is the Navigator uses 4 valve heads and the F series don't, but the blocks are still the same though. The special tooling used on the Cobra R was for the heads, and FPV couldn't get them as they were stuffed, but they managed to get the upgraded Cobra R versions anyway, but I still have no idea which american vehicle uses them as when they were first installed on the Boss motors they weren't used on any other vehicle, they were unique to the BA, but i'm sure they will have been used on something else as why else would they have bothered to upgrade the Cobra R heads if they weren't going to be used in the US.
