Hey guys,

I have a 1961 235 engine running on 6 volt battery still with standard coil, points, distributor. My question is: what is the best dwell angle to be achieved for this system/engine?

I hooked it up to a dwell tachometer the other night and was getting right around 29 or 30. I have read some say these earlier engines on 6 volt should aim for closer to 40 for a better performance. Others say between 28 - 33 is good. What do you guys say? Right now the points are gapped at .016 to achieve 29/30 dwell. I realize reducing the gap is what would be required to get higher dwell.

Also, one guy said the spark plugs should be gapped at .40 even though most manuals I've read say .35. What do you guys say?
