NGK FR5 V power?
I'm currently using Bosch Platinum plugs in my Commando 273. I used Champion N12-YC for years in my small-block Mopars without a problem, but had heard some bad things about their quality these days. The Bosch plugs have been in for 3 years now with no problems, I just check the plug gap occasionally.
I run 7's
Ok. I got a bone stock 71 340 with J heads, mild cam, and factory points. Think the 5's gapped at .035 would be ok?
In response to post 26;
One time, back in the early 80s, I was doing a tune-up on a Chevy pick-up. I cant recall the year of that truck, but I do remember it was HEI. Anyway I put a set of Champions in it;direct crossover from the emissions tag.Well that thing ran terrible. Remember I had just done the ignition; wires plugs cap, and rotor.And it wasnt running bad when it came in. So after reviewing my work and finding nothing wrong, I decided to put the old plugs back in. Like a charm, it ran nice again. Well I zipped over to my supplier and got some A/Cs. Installed those and she ran just fine.
Now, I cant really fault the Champions cause they work very well in all my Mopes.It might have been several bad Champions. I reasoned that was hardly likely. But ever since that day, in GMs I only put A/Cs, Fords get Autolites, and Mopes get Champions. I cant say right or wrong. Its just what I do. Never had a problem since.
1st let me say this is just my opinion, but Autolite Plugs are cheap junk. I have learned this over the years with having cars come in running like crap only to learn the owner tried to tune up using the things.
I've seen many a mopar puke the wrong plugs, put a good set of Champions in and your good to go.
I've come to learn, Champions and some NGK's in Mopars, Motorcraft in Fords and AC's in GM's. Bosh plugs go into Euro trash and there is a plethora of stuff if jap cars. I also know the company that owns NGK also owns Champion.
but the one thing that seems to be common among most all makes, Autolite plugs just don't get the job done.
My father, who worked for GM, Showed me why AC plugs were superior to the others. Was a few years ago tho. I still use AC plugs. MT
So Enlighten us:happy1::dontknow:
BTW Champions here
