I am intersted in an electronic ignition conversion for my 77 308 GTB. can you steer me to the proper people to purchase this? Also interested in the Millermon single dist. conversion. Thanks! |

That was my thought exactly... all these devices do is replace the analog points with a digital point system. Then no point adjustment is needed. I am an electromotive seller, but for those who want to keep things looking stock with an improvement, the Pertronix should be a good alternative. |

Erik I had a Pertronix conversion done last year by a guy in Ca.I have a 77 308 GTB and what he did was install 2 Pertronix's units in 1 dist. so all you needed to do was time 1-4 and 5-8 were in sync. The setup is simple and still uses 2 dist. and the tach works without any amps. The second dist. has no points or pickups but is used to dist. spark to 5-8. Runs great. |

Good point peter, back in the late 70's this was true do to coil technology. However, now days with MSD and capacative discharge 1 distributor is fine. Thats why I started making the Millermon Conversion distributors was to get away from the Cap&rotor costs. By the way both an amplifier and a 2/1 splitter is needed to make the tach work correctly. |

Why are people so bent on ditching the twin distributors? I've had no problems setting the timing with either points or the Cranes. Both dizzy's keep accurate advancement. Having twin distributors reduces coil saturation (ie: more dwell time to recharge the coil. This is why even with the single dizzy, it remained, essentially, two separate distributors with the bi-level rotor). Why do you think there are so much of these "Hi-power" coils for American distributors? Just because of that little time between each firings, you need all the juice you can get. Regular, off-the-shelf coils installed with the Ferrari's twin dizzy set-up makes a marked improvement.

I run that unit in my Europa. Mounting it was a pain as it wasn't tight and caused a miss, and it didn't fit right even though it was supposed to. Probably Lotus related though. Now that I have it working it seems fine but no better than points. Perhaps over time I'll learn to appriciate it more. Oh, and be sure the magnets are tight. They've been known to become loose. |

I had Bob Norwood convert my 77 308 to a single dizzy electronic ignition right after I bought it...
One of the reasons I went with his conversion was because it gives the appearance of a Euro style engine with just one distributor, a look I like.
It also does away with the stock Ferrari cap and rotor which saves money come tune up time, which is something to think about.
With the Pertronix system you will still have to pay Ferrari prices for the caps and rotors...
If I had it all to do again, I would go with the Electromotive system and never have to buy another cap or rotor ever again.
The one other down side of using the Pertronix or Crane systems with 2 Dizzys is that even though you have replaced the old points with a more modern system, you are still in affect timing 2 four bangers...
With the single distributor, or the Electromotive system, all eight holes are locked to one timing signal...
Just something else to think about. |

I would make sure they have a solution for the tach signal also. This may require a an amplifier circuit to boost the signal. Also don't forget that the tach signal for most 308's is half the number of pulses as some systems because it is read from just one distributor. Better to have all this worked out prior to the buy IMHO. |

I have been communicating with Pertronix and currently they only do one off production for the 308 at a cost of ~300 per distributor. For those not familiar with Pertronix product- it replaces your points and condensor with a Susan B Dollar sized unit which resides inside the distributor. The only thing anyone notices is 2 silicone 16 ga. wires coming from the distributor vs. the one stock wire. It uses a hall effect sensor and a magnet ring to pick up the timing lobes.
I have been using Pertronix for 10+ years on my 914 distributor with only positive results- no points or condensor to ever replace, timing never gets off and no dwell to set. I am hearing they are similar to the Crane unit- but don't have the large external unit mounted under the coil. There may be a possibility that they can make a dual trigger system so only one unit will trigger both coils- therefore you only need to time the one distributor once.
If I can coordinate a group buy, how many of you with carb cars would be interested? The typical retail for these units on all applications is less than $90 so if we were to make it worth their while to make a lot up, we would benefit.
Thanks
