Thread: spark plug brand

Tweet

Hey guys, what kind of spark plugs do you use? Champion,AC, Accel, Autolite? What do you have the best luck with? I have a set of Accel plugs in my 350 and they suck. When I went to tighten the screw on top the center electrode spun. Didn't like that but I started the motor anyway 'cause it was all I had.
Need your opinion please. Russ

i just use standard autolite's 86's most of the time, colder for the track hotter for the street is the rule to live by hehehe 85's at the track........ just dont use autolite wires

I had exactly the same experience with Accels. I pulled them out after a very short time and slid in motorcrafts (it is in a Ford 302) and with a Unilite distributor and Accel Super coil, I just changed them after 3 years, and they still looked good.

I'm really surprised at the Accels.

accells pop to damn much. my friend had some in a his truck they were popping i said dude take em out and get some autolites he pulled out these old autolites put those in stopped popping

Either Autolite or Bosch.......works best for me......Oh yeah, I always index my plugs, too....

Does Accel make anything that isn't a pos?

Well, yeah, their decals are kinda nice......

Can you give me an Ac or Autolile # That is good for a 350 Chevy?
Good old 010 block, Good old 186 heads, Like a J11y Champion
but Champions suck. Thanks for your input, Russ

wanna sell those heads?

What motor you runnin' gassersrule

283 bored .125 to 301 4 inch bore 3 inch stroke

I think it would cross to an Autolite 75 or 85. Usually better to check by application though, and not cross reference. Go with the book recomendation for you engine, then adjust up or down to get the correct heat range. Might want to check Autolite.com, lots of options on different styles of plugs. Pick the one that best matches your engine and driving conditions.......

Thanks Dave,
It's a pieced together motor so I can't really go by application other than maybe what it resembles as maybe a 70 LT1. Yhanks for your input. Russ

3 inch strokes rule, Hope you hit 10500. What kinda fun you been having? Russ
