Timing with Electronic Ignition, How many degrees before TDC? Options

[Ken6432]

I have a '74 914 with dual Weber 44s and a Pertronix Ignitor distributor, with no vacuum advance on it (or mechanical as far as I can tell). Pertronix says that there is no dwell setting for their distributors. They said I would be fine using a static timing technique, but I would be more comfortable using a timing light.

My question is, how many degrees before TDC to I set the timing? Or, am I missing something? It seems I need to know this in order to set the timing correctly.

Thanks for the help.

(IMG:style_emoticons/default/agree.gif) 27 BTDC @ 3500 rpm. As far as I know, you can't static time Pertronix
like you can with points....maybe they just meant you could eyeball it to get it
running before using a timing light. I always thought that these Pertronix distributor
setups were more for Type 1 engines and the advance curves wouldn't be the best
for Type 4's. It's probably a lot like a 009 dizzy so you'll likely have to play around to get a good driveablity with it. Anyway.... (IMG:style_emoticons/default/welcome.png)
