- 1976 Jeep CJ7 Renegade - Levi's Edition. 304 V-8, T-18 granny 4-speed. 38k miles. All original except 4-barrel intake & dual exhaust.
Well, the original Prestolite ignition finally crapped out in my 40k 1976 CJ7 Renegade. I replaced it with a new HEI unti from Southwest Performance. Great upgrade and runs smooth as silk. I would think that I could extend the gap on my plugs since I have a lot more voltage. I was going to push them out to 0.050. Anybody have any expert knowledge on this? I am aware that this will shorten cap & rotor life but I may put 1000 miles on it a year, mostly off road, so I really don't care about this issue. I hope everyone is keeping safe!
