I would not excede 35* dwell max.Turn them both down a tad.
Shoot for 33*, + or - 2* max, then set timing.
I just hate to see you fry a coil. It might take all day, but you can get them pretty dam hot. 38* is pretty strong.

Large gap = small dwell
Small gap= large dwell.
Who made your distributor?
They can tell you what the dwell is.
Dwell angle is the time the points are closed.
The single point time makes 30* of dwell, with two sets of points the dwell time will be higher.

Dual points are pretty much all the same.
6 cyl and 4 cyl has more dwell, but also more time to cool the coil.
Some HP coils can take more, but you have to check with them.

OK I will try to adjust down. Thank you!

Old Accel 371000 A. I believe Big2Bird is correct. I should have set them each around 26, but for some reason I was thinking it was 29.

Don't forget to reset the initial timing after changing the dwell.
