Title: FE 427 - timing curve
Post by: priobe on February 20, 2023, 06:10:30 PM
Hello all

I would like to know if anyone has a timing curved map that they would like to share. I am looking for drivability.

I have a Progression Ignition that so far I absolutely love. MSD missed the boat on this technology, on my 427 FE with 48 Weber carbs. Currently I have not hooked up the map sensor but plan on combining all the vacuum signals to route to the map sensor.

So far the car runs a lot stronger and is more predictable and definitely has street manners.

I’m not looking to debate, but I know this works for me. I’m just trying to see how much manners I can  teach this motor and still have the power that it has.

From here I can change the mapping to be more aggressive for better fuel or reduce the aggression with lower quality fuels.

I would love to hear some feedback on this topic or distributors.

Thanks

I run everything locked and use start retard.  That includes the street/strip car.  I prefer crank triggers, personally.

Distributor curve per Ford Muscle Parts that has worked just fine for me in the past.

Distributor rpm  250       500     1000     1500     2000       2500
                        0*       1 3/4*   7 3/4*   10*      12 1/4*   14 1/2*

Initial advance 12-14*  Total timing with iron heads 38*  Aluminum heads ~34* depending on combustion chamber design.
Yes, some iron heads will make the most power at 41-42* total timing depending on the engine.
