Anybody running E3's?

Does anybody use the E3 Diamondfire plugs in these old engines? I've heard that they will mess them up. Just wanted to get some second opinions before I buy some.

Re: Anybody running E3's?

hey i have a 72 with a 427 c.i big block that was used to drive about 50 to 100 miles a week on the weekends and some racing. i had the e3 plugs in for about six months and never had a problem with them. i think it actually ran better with the e3 just my opinion.

Re: Anybody running E3's?

OK. Great! That's what I wanted to know. I figured that different plugs wouldn't hurt it. After all, a spark is just a spark right?

I just put some in my friends 440 that we built and it runs good. I haven't heard of any complaints.

I had them for about eight months in a very tired and stock 250 and LOVED them. Especially in the cold winters we have. Extremely fast startup even with points. Just don't drop them

not exactly... first off there is the heat rating, the insulator quality, copper core vs non-copper cored, etc, etc, etc...

Personally I'd stick with NGK or Denso... I've personally found their build quality to be superior... I also used to work for NGK so I am biased... haha
