I'm getting ready to do a tune up on the 350 in my burb I was wondering what would be a good plug to run? I'm running just the standard A/C's in it now, is there a plug out there that is going to make the Ol' burb run better then she does now?

RON WOODGEARD · 08-23-2002, 06:09 PM

I hate CHAMPION plugs, never could get them to last any time at all in a normal warmed up small block BUT i came across their "TRUCK PLUGS" a couple of years ago and have used them ever since, I like NGK or BOSCH "platinum tipped" normally but these TRUCK PLUGS have really passed the test for me in my 350 While I was using it to play off road with, Sometimes idling for extended periods of time crawling in the rocks or sand. Now I'll give em a shot on the street.

Thanks Ron for the repliy...............anyone else?

Longhorn Man · 08-23-2002, 06:40 PM

If you run headers, and clearance is an issue, try the BOSH supers. They are pretty short, and 99 cents at Auto Zone.

Project1970 · 08-23-2002, 09:02 PM

I've had success with Autolites and Champions...going with Champion again simply because that's the plug Scoggin-Dickey recommends for my Vortecs.

71402BB · 08-23-2002, 09:18 PM

Champions? really? The reason I ask is because I have NEVER heard good things about there plugs other then the "truck plugs"
Autolites- Arn't those made by Ford for Ford's?

Blue_71 · 08-23-2002, 09:54 PM

ive got autolite platinum something in the 4x4, works good for me.. but i wouldnt recomend AC delco plugs for anything, i have to change them out in my grandas truck every time i start it

*shrug* I've used 'em a few times over and no problems at all.

Autolites...no, those are by Honeywell (formerly Allied Signal), aka the same boys who bring you Fram, Prestone, and Bendix.

71402BB · 08-23-2002, 10:09 PM

Oh cool thanks for the good news project 70! hehe

jostrans68 · 08-23-2002, 11:53 PM

I have had great luck with the autolite Plats.. and as far as FORD making them well they finally had to get something right LOL!!!!!!!!!!!!!!!:p

Mountain Man · 08-23-2002, 11:54 PM

I have tried many different types of plugs in my vehicles. The hands down winner in my experience has been the AC RapidFire plugs. I am currently running these in my 67, with a .045 gap. They are very responsive and smooth idling. I have also had resonably good luck with Bosch Platinum plugs - they run smooth, but feel less responsive than the Rapid Fires.

Chevyman69 · 08-24-2002, 01:34 AM

I second the Rapidfire vote, some of the best plugs I have ever used, in fact the best ones by far for longevity and smootheness of running. Wouldn't even bother with Bocsh, there plugs are trash, at least mine were.

nroden · 08-24-2002, 02:42 AM

I replaced the Autolites that my grandpa used in the truck with ACDelcos and they seem to be great.

bobs409 · 08-25-2002, 07:41 AM

Just regular old AC's for my vehicles. "Keep your GM car all GM"

I really don't think there is a miracle plug to make your engine run any better.

**72 Super** · 08-25-2002, 11:19 AM

I agree with Bob.But I will never use another champion plug.I put them in my 71 a few years ago and it ran terrible.I run AC's in all of mine

71402BB · 08-25-2002, 11:42 AM

well sometime today when I get the chance I'm going to change the plugs! I guess I'll stick with the A/C's thats what I have always used and they always did work well for me. But this time I think I will try those rapid fires! Thanks for all ther replies!

TODDS 72 · 08-25-2002, 12:37 PM

Years ago A/C was for GMs,AUTOLITES for f-rds,Champions for
CHRS,NGK and BOSCH for imports.
Now thay make um for everything.
BOB your right KEEP YOUR GM GM.
I like to put just alittle HOTTER plug in the old carbed engines,
I think thay burn the fuel of today better.
JUST MY 2 CENTS.

mikep · 08-25-2002, 03:28 PM

I used to run a hi 11 second car with nitrous. Tried a test once. Ran autolites on one side and AC's on the other. Melted the electrodes on all the AC's. The autolites were fine.

*racedvl* · 08-25-2002, 04:44 PM

Hey, install a set of Bosch +4 's and forget about them!! Ask TJ, how he likes the set I got him!!

71402BB · 08-25-2002, 08:49 PM

Well I did the tune up today! I didn't end up running the rapid fires cause Napa didn't have all 8 of them and did't have 8 of any other platnum plugs either! Damn!! So I ended up running regular R44t A/C's.......seems to be running better, but is still burbing oil...............thats a whole nother story!

Burbing? Is that a speical suburban thing? LOL!!

gabet40 · 08-25-2002, 11:49 PM

i just replaced my a/c 44s with the H/P Accel shorties. im sure the 44s were short enough for the new Sanderson CC10 headers i just bought, but i figured why not try something different. in the process i had to change to 90? boots so i stepped up from Accel super stock 8mm wires to Accels 8.8mm spiral core wires.
a little more hp and less hesitation off the line were the result. plugs, wires, or combo? i dont know, but it worked
