Six Cylinder Flywheels:

Flywheels And Starter Plates On Holden 6 Cylinder Engines:

All Holden grey/red/blue and black 6 cylinder flywheels fit the crankshaft in one position only. If the flywheel won't bolt to the engine, keep turning the flywheel (with the crankshaft stationary) until the flywheel bolt holes lineup properly.

All Holden grey/red/blue and black 6 cylinder starter plates fit the crankshaft in one position only. If the starter plate won't bolt to the engine, keep turning the starter plate (with the crankshaft stationary) until the starter plate bolts holes lineup properly.

Red vs Blue Flywheels:

Submitted by v8slrtorana on Wed, 21/03/2007 - 08:21. You can bolt either flywheel to either motor, crank bolt patterns same.
The red pressure plate will not bolt to blue flywheel and vice versa.
The blue flywheel is lighter from memory. Maybe to compensate for the extra weight of the blue clutch and pressure plate.

Black Six Cylinder Flywheel:

The Black 3.3 flywheel will fit a Red 202. They are lighter than the red flywheels.
Blue/Black pressure plates are larger and heavier than the red units.
The larger pressure plate may foul on the inside of the red bellhousing(at the top), particularly if it has a mechanical (push type) clutch linkage. Cheers, Jeff.   Red flywheel will fit the Black crank (same bolt pattern).
Black crank has a locating dowel that needs to be removed.
Spigot bush will fit.
Red and Blue/Black clutches are different, so fit the one that suits whichever flywheel you use. Jeff.

Red motor used an 8.6" pressure plate and the blue/black a 9.1" pressure plate. Both kits are readily available.  G'day David, The Blue/Black flywheels are lighter than a Red motor one. If you do what you propose, all you'll need to change is the Pressure Plate (and maybe the clutchplate) assuming the bellhousing you are using clears the larger blue/black flywheel. If your bellhousing won't fit over the bigger flywheel, you'll need a different one of them too...
Cheers...Dave  

Dowells:

Black 6 Cylinder Cranshafts also have Dowells in the Rear end which help secure the Flywheel for accuracy of Timing issues needed by EST.

Ring Gear:

The Ring Gear is fitted around the Flywheel to allow for the Starter to operate.
