I am installing my 2055's in a week or two... should I change my plugs to accel shorties or something while i have the headers off?

 

I have heard bad things about the accel shorties. Bosch plugs are the same size but they are junk to. Just use AC delco's and use a modified sprak plug socket. With the socket I can change my plugs in 10 minutes.

 

I have used the accel plugs and they are actually pretty good, but I am back to the Regular AC Delcos which are just as good now.

It helps having the shorter plugs, but probably not worth the $30 pricetag.

All you have to do is use an open end on the hex part at the head of the sparkplug socket and the back plugs come out real easy.

 

I have hedman LT's and with the TFS twisted wedge heads, they are the only plug that fits. When I first started the engine, the thing was so rich (to much fuel pressure, long story) that it was dumping raw fuel out of the tailpipe. The plugs never fouled...they are great plugs imho. Hey, if car craft likes them, good enough for me!

 

I hated those accel POS, the little end kept coming loose all the time, not to mention those were the only plugs i ever had in which the entire plug would come lose on its own... those are probably the only aftermarket thing i have ever bought that i would strongly advise against anyone buying. I have tes headers and i just use ac delco rapid fires. i can get to them fine with just your average plug socket (have to use a wrench on some).

 

I've been using 276S since Nov '01. I replaced them in Nov '03. Starting last summer, I had one plug that kept losing the screw-on terminal. I finally figured out the wire wasn't snapping on hard enough to keep it in place. I replaced the wires when I replaced the plugs.

I happened to have the plugs sitting around back in '01 from 1996 (Summit SBC headers for the '57 thing). I had two sets due to an order snafu. So, I haven't purchased them recently, therefore I don't know if there's been a quality decline in the past 8 years or so. But, I don't have any complaints with the ones I've had.

Replacing them - well, that's a chore with the 2055's, no matter what plugs you're using. And I did it last with no A.I.R. in the way.

 

ive been using the accel shortie heaer plugs for about a yr almost and no problem. i gotta change them just for the knowin of havin good plugs in.

 

Mine have never came loose on their own. Sounds strange, any idea what would cause this?

 

I suspect it's wire boots that are being held on by the boot on the ceramic only rather than the boot on the ceramic and the wire clip on the terminal together.

 

I picked up a set of shorty accels and notices they are almost exactly the same size as the Autolite 605's I was running... In fact, I think they were the same length. Not nearly as short as I was hoping for

 

The Accel plugs are the same exact plugs as the NGK U-groove plugs. I've used them and had no problems at all. The only reason I used them was the fact that they are shorter and readily avail. I have since switched to the Autolites due to the fact that they make some of the best race plugs out there.

 

2055's + spark plugs = minor insanity

 

Vortec heads + Hooker LT's + #7 cylinder + any sized spark plug = MAJOR insanity Theres not even enough room to thread the spark plug into the head unless you bash in the tube

 

Okay, you win.

 

maybe it was just the set of accels that i got but it was almost like they were made to really shi*ty tolerances or something, it was always the same few that would completely come lose from the head, i would say it was my engine, but as soon as i went back to ac plugs i never had that issue again. i really like the rapid fires though, better than any brand i've used.

 

are there any issues with using splitfires with dynomax headers? (I'm not trying to start a spark plug debate by the way)

 

hooker long tubes and straight angled 305 heads + number 7 tube pita but i solved that by makin my own plug and everything fits very nicely, i can get a swivle socket in there piece of cake.

 

I would reccomend a set of locking header bolts. They are $30, but they cannot come lose. My dad kept blowing header gaskets, until he got set of locking header bolts.

 

I think that that is the direction that I am going to go in.... it's too bad my damn 2055's are backordered. Grrrrrrr.

 

I use the NGK u-groove plugs and love them. They are the same length as the Accel's but the terminal end is not threaded like the Accel's. I had the Accel plugs in my old truck, and every oil change I'd have at least one with a loose terminal on it. They are good plugs, but watch the terminals.

 

Anybody tried a spot of loctite on the treads and then tightening the tip on with a small pair of pliers on the Accel shorties? Mine haven't loosened up yet, but its been less than 1K miles on the new motor....

 

loctite is not a good conductor......

 

Not to mention that loctite recomends only one main process to undo their product... heat.

I believe that I read somewhere that the headers produce enough heat to make the loctite ineffective.
