Hi all,
Just a quick query about distributors.
I have a HQ GTS Monaro with a 253 and on the weekend made a small discovery while changing dizzys for historic rego.
While removing the electronic ignition dizzy that I currently had fitted, I noticed that if I removed the large distributor cap and the plastic base under it, then the standard HQ cap and rotor button fir straight on. It looks standard but is electronic.
Why would there be such a large cap fitted to the dizzy if the smaller type works fine.
Any guesses what this electronic distributor would have come from. I though it was an early commodore one but maybe it's HZ or something. When did Holden start fitting electronic ignition to their V8's. I thought it was with the VB Commodore but maybe I"m wrong.
I am after this info as I am restoring another Monaro and would like to run the same set up. ie looks perfectly stock but is actually electronic. Saves setting points etc.
Thanks in advance

They fitted electronic dizzys from VC onwards. The larger cap maybe due to a higher voltage spark but later on in VS a smaller cap is used so that may have started on the VN's.

The HEI came in on the blue motors in the VC.
It ran thru to the end of VL on carby models.
The EFI 5L had the small cap right through.
I think the large cap was to allay fears that the high voltage spark could jump across neigbouring terminals in |

period accessories with proof ( old wheels magazines etc.)are usually allowed on historic reg cars with limitations of course , Transistor electronic ignition has been around since the early 60`s for holdens and providing it looks period to the car can be

I run a HZ tonner with a HEI dizzy, but use the small cap as the large cap fouls on the brass vacuum tree. This has been the practice for a long time as a lot of cars have clearance problems with the big cap. Mine hasn't missed a beat - plus caps are heap |

Thanks for all the replies people.
While I'm pretty rapt to be able to have electronic ignition yet still retain factory looks, I still don't know what the dizzy originally came from.
I thought it must have been a commodore one but then again maybe

The dizzy will be out of a WB or VC/VH/VK. Points dizzys can be modified to electronic using a Bosch kit that uses an ignition module same/similar to the EFI 5litre. The kit comes with a Hall effect pickup and modified rotor button. I haven't seen one for |

Hi Guys.
As Byron said, there are/were a few kits available to convert the old Holden V8 Bosch points type dissy to electronic, but after conversion they look the same, great for historic rego. I can still supply them new if required.

Thanks for your imput so far guys. I will endeavour to get some numbers off the dizzy this weekend and post them here.
It would be great to find out exactly what it is because as I mentioned in an earlier post I wish also to run the same set up on my HQ

I have a 253 V8 and put and installed electronic ignition.There seems to be lack of power and a petrol smell.What is the right timing to use.Previously I had aScorcher distributor with two points.That seemed to have more power.

Hi vhgrob.
I had to do a bit of homework on this one. The rotor to use is the Bosch GB786, which originally fits all Ford V8s (with electronic ignition from '76 to '84 (XC-XD-XE-ZH-ZJ-ZK-P6-FC-FE). The Ford 6 cylinder motors in this same period use any |

I tried to buy a Bosch kit for my original dissy but Bosch no longer sell then. I ended up with a VH dissy and kept the big rotor cap on it. quote:
