If I had a single point cam sitting next to a dual point cam, what differences would I be looking for?

Thanks Dizzy
Appreciate the analogy to cam lobes. Helps me understand why the crest is there.

The hipo distributor has a 8 sided cam that opens and closes the points. Understand when points are closed, the coil is building energy and when the points open, the coil discharges the energy to the appropriate spark plug. Looking at the flat spots on the points cam, the flat spot is not completely flat. It has a very slight rise in center between the high points on the lobe. Looks like the slight rise would start to open and close the points before they reach the point when they are supposed to open. Almost like pulling bow string back 3/4 of the way before it is pulled all the way back. What is the function/purpose of the slight ridge between the flat spots?

I think I will play safe and install a 2A inline fuse as you suggest. My Tach works and I really want to keep it that way. If I do move to Pertronix, I sure don't want to fry a original yellow top coil by throwing too much juice to it. Think the Petronix Ignitor will function properly using the resistor wire. They recommend full 12V for max spark. Will give them a call .

Hi Bo
Isn't the dash mounted tach on a 65 GT350 connected to + side of coil? Wonder if increased coil voltage would possibly smoke a Cobra tach.

So I should be fine by leaving 6 inches of pink resistor wire on main disconnect plug under the dash and replacing it with a normal wire between the ignition pigtail and the new pigtail on main disconnect plug?

When installing a Pertronix Ignitor II or III module that really needs full 12volts, do you continue to use the pink "resistor" wire that's connected to ignition switch and main disconnect and tucked under the instrument panel or do you disconnect the pink resistor wire behind the ignition switch and splice close to main disconnect under dash in impossible location?

I am looking for a 65 Hipo Dual Point distributor shaft. Prefer NOS but would look hard at a really nice used one. Have the points cam, cam gear and collar. Just need the distributor shaft. Also looking for 2 NOS lower distributor bushings. Dizzy is C50F-12127-E FoMoCo

Thanks

What gap and Dwell will you use when you replace the points?

65 HiPo 289 dual point distributor. Am told total dwell is 30-33 degrees. To get to 30-33 degrees total, primary points are set to 27 degrees dwell while secondary points are blocked off. When 27 degrees dwell is obtained on primary points, remove block from secondary points then adjust secondary points to get to the 30-33 degrees total.
Are the above dwell numbers accurate?
Looking at the dizzy pointer, shaft rotates counter clockwise. Primary points are the ones that open just before the other pair. If correct, the primary points are at the end of the strap connected to the other points and the condenser just before lead exits dizzy case.
Any comments/corrections most welcome.

Other than the resister, what is difference between the 64 , 65 and 66?

Time for a Deputy Barney minute. Nip it in the bud or pull out the single bullet in his shirt pocket. Been on this site for YEARS and have obtained so much spot on advice from so many. Someone put something in the cool aid or change dosage of meds? We are really chastising someone for misspelling a word. Geez. Move on.
