Hi,
I'm having a set of new ignition leads made up for my '69 P5B. Can someone confirm the correct lead lengths for each respective cylinder, and also which leads should have 90 degree connections at the distributor cap end, and which should be straight? The leads currently on my car are a cheap re-pro set.
Thanks.

Thanks Phil,
I'm looking into having a higher quality set made up, but want them to appear as per OE, hence this spec. request. If anybody knows the correct lead lengths or can point me to a good quality period photo of the engine bay showing the distributor cap and leads, that would be much appreciated.
Regards

I'm also having a set made for my P76 powered Mk3. The engine is a couple of inches wider across the heads (longer stroke) but everything else is in the same place.   The coil lead is in the middle of the group of wires on the right of the picture with the coil just in front and beside the LPG convertor. The leads are separated with cable ties. |

(Ok...this is bit of tech is for the Nerds and the Anal retentive on the board. You know who you are. ) I picked up my new 'leads' today and they are very nicely done. What is impressive though is the OHM rating of the leads (LPG requires a healthy, consistent spark at the plug) If you take a look at the multimeter setting (2000 Ohms) the reading on the longest lead is 872 Ohms. These are still suppression leads! Normally leads are measured on the 20,000 Ohm scale (multiply the number shown the multimeter screen by 1000) A good set of leads (Top Gun) have a designed linear resistance of 10K Ohms per metre length. The resistance specified for a Holden Commodore V6 is 17K to 23K Ohms from the shortest to the longest lead.    They are expensive leads though. ($132 AUS) Note:Due to a lack of clarity for the non anal retentive, 10K or 15K is an abbreviation for 10,000 and 15,000 repectively. So if the resistance of your leads is within the ball park of the resistance specified for a Holden Commodore V6 (17,000 to 23000 Ohms from the shortest to the longest lead) you should be ok. But, you can get better leads if you are willing to invest a bit more! |

Post Script:
Since installing these 'new' low resistance leads I've noticed a remarkable diffference in starting from cold and also in engine running & idle quality. Some mornings have been 0 degrees here and the car starts remarkably well given the need for a much more effective ignition on LPG.

Ive only just read this thread and I just wanted to comment on your new leads Vince. The white lettering really takes me back to the eighties when the fashion was to add white lettering to your tyres! I did it on my manta and definitely made it go faster  The white lettering on your leads has stirred the same old reaction in me..I WANT white lettering on my leads..it will definitely make my car go faster...>>>>>>>>>>>>>>>>>>>>>>>>>>>>>.................. Love it! |
