Sure the pain in the ass factor of adjusting dwell and replacing points/condensors is just about worth the expense - but is there any other benefit to them (besides point bounce at high rpm)??

I have a dead CHT, so it's one of those while I am ordering things....

i just put in the crane xr700 in mine today and it does make it a better running engine. IMHO, ditch the points and convert, it's worth it.

Electronic ignitions are less susceptable to distributor shaft wear. More smooth at higher RPM ranges. They boast of increased spark gap (ran my stock engine eith pertronix at 45 instead of 35). No maintenance.

Down side, they will burn out if you hook it up wrong, and they can die if the ignition is left on for long periods of time.

I had a problem with the points closing up quickly. We put a crane in it and I (IMG:http://www.914world.com/bbs2/html/emoticons/wub.gif) it! I wouldn't go back. I do think I should carry a second dist in the trunk with a points setup, just in case, but then I was a boy sprout way back when. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

That's good enough for me! The crane unit is double the price over the pertronics and compufire, any chebby places offer it for less (summit or whatever)??

I put on a pertronix a few years ago. Simple install. No module, as opposed to others. If you get one with a module, dont mount on the engine. I went thru a couple of those years ago, back when they were Allison. The module cant handle the heat/vibration.

btw, you say your cht is bad. Had that happen, too. Isn't that weird? No moving parts. wtf?

PERTRONIX - awesome


Ok, everything is perfectly clear now. (IMG:http://www.914world.com/bbs2/html/emoticons/Yack.gif)

Points aren't evil. They are easy to maintain, and they work just fine. Take care of them and they won't let you down.

But yes, a modern ET system is potentially better.

Glad that clears everything up.

And now for something completely different.

wrong coil resistance may burn up the compufire. follow the instructions precicely. if you put one in and it cranks, and cranks, and cranks,... put the points back in.

right aaron. just a heads up. i failed to due so and burned up $70 worth of a module when i was putting the 73' together. i spent 3 days chasing a "no start/no spark". the solder melted out of the bottom was appearent when i pulled it. couldn't see it when it was installed.
