Changed wires,cap,plugs,rotor. It seemed to run out of power too soon and didn't idle too well. (Of course the Shankle EG rally grind on the cams made it sound like a drag car at idle. The HC at idle were around 4000 ppm  The engine seemed to fall on its face at around 7 grand.
Long story short. I finally called some one at MSD. The guy I spoke to was very sharp. He says the MSD has TOO much spark for the Small Alfa dizzy cap. It was jumping spark across the inside of the cap causing spark to reach cylinders that weren't ready for spark. I went back to the OE set up using the MSD Blaster coil. The Idle improved, the HC at idle dropped to 2900ppm. (The cams  )
The engine was able to pull hard at over 8000 rpm (had it to 9400 at an auto-x once. Oops)
I would install the Jacobs if I had a choice.I installed one on a buddys Toyota truck and it made a world of difference. Power, mileage,etc improved.
I think Jacobs is more modern and up to date.

I, like Erik, have been running the MSD 6AL for several years. I think it was probably just the box malfunctioning Paul. Erik and I are proof of that. I have had it triggered off the points distributor as well as the LED RML unit. The MSD guy looking to blame the car rather than his box.
To Mark:
Come on up then!!!!
To Erik:
Check out these. I wonder if the difference is from the stock system falling off at upper rpms. What do you think?

Sure, the MSD box you had might well have gone bad. But there is nothing incompatible with the MSD and the Alfa ignition. The MSD tech should know this.

That is usually over looked, a more turbulent head hates advancing, but loves and uses more volts to fire the plug under load. That is more than likely why they got such a good gain in power with the electronic set up-hotter spark to go along with a turbulent head.

David,
Could you explain what sort of performance gains your expecting over the stock Motronic ignition that came with your car?
