My brother has a 74 914 2.0 that's going to get a 83 3.0 SC installed into it.
The engine is going to be run with Weber carbs. I know that some members may have a 3.0 installed in their 914's . The question that I have is what type of ignition source are you using? I've heard the 83 distributor cant be used and need to use an earlier one ? Can a MSD 6AL box, & coil be used instead of the cd box? The engine wire harness what's needed to make this work? Any help would be greatly appreciated. Thanks, Luke |

I was planning on hitting up the guys on the Bird board later today.
The p/o told me I couldn't use the distr because there's no mech advance and to use an early 3.0 unit. I'll do some research hopefully come up with an answer. Thanks |

There is the MSD AL6-2 programmable, you lock out the dizzy and program the curve via computer. USB update so you don't need a laptop. They have had problems with the small cap 2.0-2.7 dizzy's phasing but a 3.0 cap and rotor are larger so maybe it would be OK. |

I'm relatively certain that the later dizzys don't have enough total advance to properly run on a carbed motor. My carbed 2.5L 6 runs around 35 degrees total advance and I want to say that those later SC dizzys max out at 20 something degrees BTDC.
A MSD and coil will work. |
