What spark plug are you guys using in your 440 engine ? Thanks

I've run Champion's forever without any issues.

I use the race NGK's found they have a better heat range for my applications all the champs I bought ended up with micro cracks and leaked spark to ground drove me nuts troubleshooting the small misses at different rpms ug. I think having headers doesn't help champs they are perfect for stock set ups.

champions in my 440

Champion RJ12Y's forever in all mine, B's and RB's. I've got new ones for my 440 Source heads, forget what they are (whatever was recommended, after market heads are DIFFERENT!). Quickbird has NGK's in his new build of the real big, big block. It's actually running now after last weekend. It WILL be at the Columbus GG show and the MOPAR NATS (needs tons more work). He needs to work on it instead of running off to party for the Memorial Day weekend. Mine will be together before too much longer. Too many events getting in the way!

"video unavalible" (whilst I scramble to find another yellow '69 road runner in the Columbus area so I can get this guy off my back).....:jester:

 

[quikbird]

I give up with YouTube. That is the exact address it gives for the video but then it says it can't find it. What a crock!

Nothing wrong with them in the past but they are made in China now.

I have run just about all major brands and found the RJ12YC to be my favorite.

.035 gap?

 

[Ranger]

Correct

 

[quikbird]

if you jump up to some of the hotter coils, bump the gap a little to .040 or so.

 

[moparchris]

Yeah .035

Every motor is different and each has its own preference. I usually use Champions in everything. Just because one works for me doesn't mean your motor will prefer it. I found the Champions resist fouling better than most. You should try a few different brands and see whats most important for you.
