i dont really understand the difference between them and why they were dizzy (a b d) when to coil (f) and went back to dizzy (L)

my idea of a coil pack is like what the commodores have. anyone explain it to me a little better?

A coil pack is a bank of 3 coils together and can develop a faster stronger spark.

Dizzy's worked for 50+yrs and proven reliable (when maintained) and only have one Coil doing all 6 cylinders.

And in EF's the idea was to 'get rid' of moving parts and i guess be 'up there' with the compeditor and have a more advanced safer timing system with a knock sensor, and was controlled by the ECU with info from the crank angle sensor and camshaft sensor.

I think in the EL series they cut corners ie: no painting of block and engine bay and using left overs ie: dizzys. But i cant really back that up can I :P

Either way.. i think the EL is more user friendly for us 'modders' as timing can be messed around with to an extent.

and for the AU.... i think they found there could be more potential in a coilpack and back to it they went?

thanks Krytox.

btw the late EL's had the au heads. they put out the same power right? el vs au?

yeh hybrid heads... lower rocker ratio and different ports/springs

Some say they have more 'meat' in them... and are best suited to LPG as for the ports..
but I dunno.

other than that, same output I'm lead to believe

Thats what I heard, Ford trying to keep the price down so cut some corners.
However in my EL the engine & engine bay was painted, in the BA they are not!

The EL hybrids didn't get an increase in compression or anything so they were the same power output - and krytox only the EL2's had the unpainted engine bay, the sereis ones are painted.
As far as I understand it, they changed to coil pack for the reasons krytox suggested, but I don't think it went exactly how they wanted it to? So they put it back to R&D and reverted to the dizzy in the meantime.
