New ignition system
New ignition system
Well it’s been a while but I’ve finally got the 440 back in the truck and running. I had to replace all the wiring due to it cracking and shorting out all over. While I was doing that I bought a Mallory 6al and unilite distributor. The distributor doesn’t have vacuum advance and I am wondering if anyone knows about where the timing should be? I haven’t really had time to play with it but so far I have it set at 14 deg initial and it seems to be running pretty good. Is there anything I should watch out for with this set up? The motor is bored .030 and I’m running CNC ported 516 heads with a 232/245 518 lift cam.

Of all the 440s I've had with iron heads I haven't seen one that didn't want 38 degrees total. That said initial timing could be a little more maybe 16 degrees with the total all in by 2500 rpm. I would try a little more timing a/ idle and limit it to 38 total, you can always go back to 14.
Good luck
