What do I time my SBC with a mag to?

This is a standard Vertex Mag with no advance. I have run this set-up before and the motor ran great. I need to know what to set the timing at however initially as I don't now remember what it was set at prior.

Thanks, Tim

 

I set mine at 36 total, my mag is locked up , meaning the advance stays the same all the time, a little harder to start but sure runs good.

 

If I'm not mistaken you need to gap your plugs about .018 don't ya?

 

Wherever the motor is "happy". They're all different.

 

yes I gap my plugs at .018 ,timing at 36 and my solid lifters are at.016. and be sure to run the old solid wire core plug wires also, we did a check and the suppresion core and solid graffite cores don't conduct as much voltage. 7 mm works best, oh and ps watch touching the ground post while running, or you will have pee running down your leg!!!

 

which heads you have might make a difference, newer design chambers seem to need less advance

 

I run one on my sb and I set it up until it kicked back and then backed it off a red one, and it runs great.--TV

 

Thanks again guys, this weekend I'm going to slide 'er in. It's a cool one with a cable drive tach.
