Here is the link to the thread, I suggest reading it, it has very good information regarding the drop in of SHO rods and pistons.

http://www.rangerforum.net/forum/showthread.php?threadid=13624

Here is some information about the 3.0L Vulcan engine that may be of use for you guys:

SHO Crank in a Vulcan:
Auto Trans: use AT 3.0L/3.2L SHO Crank and rods.
Man Trans: use only the 3.0L MT Crank (otherwise you will need a custom flywheel/flexplate, or welded/redrilled mounting holes in the crank).
Mix and match pullies/harmonic dampeners to fit. All rotating assemblies must be balanced due to the swapping.

(Numbers are as printed in the Ford Motorsports Catalog 2001.)

Pistons:

Vulcan: 3.504" (cast/hypereutectic), available up to 3.544"
SHO: 3.504" (Forged Only) SHO block can accept a .122" overbore to 3.2L!
Pinto 2L: 3.575" (all versions)
Some Chevy (corp.) V-6's are 3.540 and larger

Rods:
Short rods= low rpm/towing, quick to gain RPM's, but can't fill cylinders well. Need larger valves and tall (3.45:1) gears, in town, daily driver, high torque use.
Long rods=high rpm/horsepower, better at filling cylinders, less prone to detonate, more stable at RPM's, likes short (3.73-4.10:1) gears. Highway and high RPM use.

Rod journal diameters
Most all Ford and the Vulcan: 2.123"
SHO: 2.047"
SBC Chevy 2.100 or 2.000"

Rod length
Vulcan: 5.5315"
SHO: 5.780" (same as 351C/4v/HO/Boss/Cobra Jet!!)
302 (5.0L) strocker rod: 5.400"

And some more stuff:

Block Height 8.6610
Stroke 3.1496
Crank Offset 1.5748
Crank type Cast
Main Journal 2.1250
Rod Journal 2.1230
Rod Length 5.5315
Piston Height 1.5354
Piston Pin 0.9122
Deck height 0.0193
Bore 3.5040
Bore Spacing 4.330
Displacement 182.23 2986.78 or 3.0 Liters
Head CC's 47.1 - 50.1
Gasket Bore 3.5750 (Mean taken from 4 places on actual gasket)
Gasket Thickness 0.0400
C/R: 9.33:1
Dispacement Ratio 8.33

From Ford Racing Performance Parts 2001 Catalog and actual measurements

What about the camshafts? Or would it better to just be better to get the boss mustang roller rocker arms bolted on....maybe both?

I am not sure but isn't that a sohc engine? If so, I would check out the rockers from the 281 4.6. These engines are readily available and any modular engine starting from the 92 crown/marq to the 2001 4.6 and 5.4 are identical. Also thanks for posting that info, I have just found the answer I have been searching for. Where to find a flat top piston to fit the 4.6 that has a bore starting at 3.551"

The rockers from many Ford V8s and even some Chevy V8s will work, Fredness over at Rogueperformance has actually come up with a Cobra Roller Rocker kit that will drop right into the 3.0L Vulcan and still have enough valve cover clearance..... He had to do some slight milling but it worked.....

With Roller Rockers:



Factory Rockers:



Fred has actually run with these rockers thousands of miles, and so have a few others that have done it. He will have some new sets of rockers available probably sometime in January...

Is there any difference between the 3.0 vulcan from a 96 taurus and the 90 probe. I think that it had roller rockers. Of coarse no where near the potential of the cobra ones

No it didnt have roller rockers, you are thinking of a roller cam. That is one way that it produces more power than the old school 3.0's...

more lift according to the guys at the ranger forum it makes like 6-10 hp to the wheels

whoohoo

oh by the way the sho crack needs LOTS of machining to make it work since the thing is longer than ours and some other stuff

All 3.0L Probes from the factory have Vulcan engines. It's just a name for the engine similar to the KL03 or the KLZE.

What is the difference between the Vulcan 3.0 and the other 3.0 and how do I tell the difference to know what I have in mine???

whoa hey how much will they charge for making a forged steel crankshaft for our probes, also as far as the piston goes you will need to have again forged steel ones cause otherwise the ones that we have will eventually melt and break which is not good my friend go the rangerforum.net they know their shit about the 3.0s

They have hyper pistons which might not be as good as Forged, but they will help. Also, check out some of the other stuff they've got that would go nice with an engine buildup like this. Another good place to check for stuff like that is SHO Shop, but I am not sure if they specialize in 3.0 parts that much. But I do know that Morana Racing does and they might be able to get the forged cranks and stuff like that.
