I just use the flap on the cardboard box the points come in to set the rough gap. On a manual trans I’ve just left it in 4th gear and nudged the bumper to get it on the high spot. Set it with a dwell meter after it’s fired up

That was my issue and why I used a feeler gauage; just what does the thickness of a matchbook even mean in 2023 and as I live in the UK how does it compare? I know it did not need to be exact but just wanted a good starting point particuarly as I had the distributor on the workbenach and hence easier to set up before I fitted it.

Along that line, my suggestion would be to start at a 0.020" gap, then after installation in the car, with the car running, I seem to recall that the dwell angle is 30*.

From a little research on Google and from gathering info from the Forum its seems .019" is the recommendation for a 454 (1970 car) and as your unlikely to find a .019" in your feeler guage fan 0.020" will be good starting point, and then from other comments 30 degrees appears to be the setting for correct dwell.

I didn't say matchbook I said flap on the box the points come in. What does it mean in 2023? Good question. Answer is: about what it always did. I'd still check the dwell with a meter feeler gauge or no from habit.

Before anyone has a canary, I run Echlin points and capacitor, These were just handy in the 'get you home' bag. Which I haven't ever needed. Yet anyway.

  • Sorry, didn't mean to do any hair raising, just inject a bit of nostalgia. Hope you get your gap set up okay...

I'm not the OP but no worries from me. I just thought if I actually showed the stupid flap trick someone might believe me.

Hair raising? Really - no worries there ! no hair left to raise
