Re: [Chevelle-list] Spark Plugs
I generally run AC Delco Plugs, but depending on how your engine is set up you could look into Autolite AR104s they are shorter to clear headers and they have a very short electrode. I used to run them in my roundy round cars and I currently am running them in my Monte Carlo, but I will advise they are not for light cruising, its kind of like running a tunnel ram on the street, you can do it but there are a couple drawbacks. If you have a bone stock ride stick with the ACs if its a little on the radical side try the Autolites. Accel makes header plugs but I've never had much luck with that whole brandname.

Re: [Chevelle-list] spark plugs
Sorry to bug you guys but I would really like to get some spark plugs into this car. The numbers I got from the heads are 14014416 and J152. Can anybody tell me which plugs to use based on that or at least what year model car these heads are likely to be from?

Re: [Chevelle-list] spark plugs
Thanks but I just went on the AC Delco site and looked up a 1980 Camaro w/ 305 and it says that the R45TS is the plug for the 305 that year, or if you want to get fancy with the platinum plugs, the 41-905. It also says to gap them to .045. I am very lucky that I didn't grenade my engine with the 41-932s. They are too long and the pistons must have hit them because a couple of them had the gap slammed shut after only about a minute of running. I said to the guy Remember when you said somebody f-d up my engine? Well the plugs you sold me could have f-d it up big time. They actually didn't want to take the plugs back because I had used them for all of 30 or 60 seconds and even though they were clean, the gaps were all messed up. I asked to speak to the owner and he said he couldn't take them back because they could mess up somebody's engine. I told him that they could have messed up *my* engine but according to his guy they were supposed to fit and they clearly don't, and I wasn't paying $50 for a set of plugs that don't fit. So, he gave me a refund and chewed out his counter guy about recommending a plug without knowing that it would really fit. Anyway, hopefully I can change my plugs in peace now. John Nasta

Re: [Chevelle-list] spark plugs
I used a 1980 Camaro w/ 305 on the Delco site and it cam up as R45TS, so that's what I got. It seems to be running much better but I only took it around the block.

Re: [Chevelle-list] spark plugs
John, I'm sure you are safe enough with either plug. The problem with recommending the right plug is that there are so many variables. Of course, you need to make sure it is the right size, which they did not do at the parts counter, but finding the right heat range and other slight variations is hard. There are experts who can look at your compression ratio, cam, heads, and drive train and tell you what plug to use for street and which one for racing. I have World Products heads on the Chevelle, and they said to use Accel 274 or 276, AC-Delco 43TS or 44TS, or equivalent which made it easy to at least find a plug to get started. I did get such a recommendation for my setup, and the 44TS is the result, so it must be pretty universal! For track days, I was told to use Denso ITF22 or the AC RapidFire #1 (this was 4 years ago). Unfortunately, you are like I was before that head swap. The engine, heads, and ignition don't match the car or each other, so going to a parts house is a crapshoot. I figured out the best car to use (I think I used a '70s or '80s Camaro, depending on what I was looking for) and told them that is what I had. Telling them a '67 Chevelle would get me nowhere, even if their book or computer went back that far! All I can say is to find the closest setup to what you have and tell them that is what you have. Use what you have now, and pull them after a bit and check them out. Compare them to the pictures here http://www.dansmc.com/Spark_Plugs/Spark_Plugs_catalog.html to see if you think the heat range is good enough. Chances are you will not be able to see anything unless it is way off or you have a bad oil leak. If you have HEI, then you can gap to 0.045.

Re: [Chevelle-list] spark plugs

Re: [Chevelle-list] spark plugs
John, I believe the 932 part of the number is the gap as set by the factory. There could be a slight mechanical difference. I trust 454 Vette Bob as he has done a lot of Chevy work. He selected the plugs based on my Vortec'd 327 description. The A41 heat range seems to be just right. I'm still using a 35 thousandths gap. -Chuck K What the guy sold me is Delco Platinum 41-932.

Re: [Chevelle-list] Spark plugs
Hey,I gap my plugs @ .060 w/ my HEI in my 70 big block I tested my Nova drag car once to see if increasing the plug gap really added more HP. The car had a MSD 7 ignition system. I gapped the plugs at .035, .045,.060, and .075. I didn't see a difference in the ETs, so I don't think it helps. What large gaps can do is to create a miss when the ignition system is over taxed and can't fire the big gap. I see no reason to go over .045 . Just my $.02 BL
RE: [Chevelle-list] Spark plugs
I think its about getting the most out of an average ignition system, e.g. a gap of 0,45 is better than 0,3 but only if your ignition is powerful enough to handle it. Those MSD 7s will ignite a bucket of water if you spit in it after a hard night in town with your buddies, even with a one inch gap... this is only slightly exaggerated... it depends on the night, though :-) Full Revs!!! :o) André -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Lessenberry Sent: 26. februar 2004 21:04 To: The Chevelle Mailing List Subject: Re: [Chevelle-list] Spark plugs Hey,I gap my plugs @ .060 w/ my HEI in my 70 big block I tested my Nova drag car once to see if increasing the plug gap really added more HP.

Re: [Chevelle-List] Spark plugs Resistor wire.
Hello: I have found the best thing with a HEI is to replace the orginal 16gauge"coil wire", with a larger diameter 12 gauge wire, back to the connector atthe firewall. I take the wiring harness plug loose at the firewall, pinchthe blade connector and remove it from the harness. Then solder the 12gauge wire on, and reinstall the blade connector into the harness and boltthe harness back into place on the firewall.

Never tie strap them to the valve covers or tie strap them together. I buy several of the looming kits, and useone for every couple of inchs of plug wire. The reward is; the tuneup will last much longer.

First, I'm not an expert on this but I do have some knowledge on the subject. The HEI was was installed across the GM car line in 1975 through 1980. After that computer controlled HEI's came in. The main difference being the external vacume advance housing. Conventional point dist. can only handle 2.5 amps before burning up. The HEI can handle 4 amps. More amps, better coil saturation. Since the HEI needs a full 12 volts to run efficiently (unlike points, 8 volts) you MUST lose the resistance wire. The HEI can produce 35000 + volts but it needs the full 12 volts to do this. (coil saturation) The resistor wire causes a voltage drop after starting. During starting it is by-passed. This wire is what kept the points from burning up. Keith is right about the PINK wire. But don't make it too long. The longer the path, the less voltage. As for spark plugs and the HEI, you should be sure to use the right application. Plugs designed for conventional ignitions should not be used because when you open the gap you are really bending the electrode at an angle. To fire efficiently the ground electrode should be flat over the center electrode. HEI plugs have a shorter center electrode. And this allows for the larger gap. Larger gap, longer spark. And don't over look the plug wires. You need at least 8mm wire. Use a good silicone and wipe the inside of the plug and dist. boot. It not only keeps moisture out but helps keep voltage loss down. Not to mention easier boot removal. A very good book I bought several years ago was "IGNITION / ELECTRICITY BOOK by Dr. Christopher Jacobs. It may still be available. I think it cost around 15 bucks. Hope this small bit of info helps everyone. Rich

Thanks Rich !!!

Paul: yes he is the one. I've seen his book for sale several places. i think maybe in car magazines and maybe either summit or jegs. larry

Anybody have the original post with the actual instructions on how to change the wiring to support an HEI? I deleted it accidentally.

The spark plugs recommended for a 1971 Chevelle is AC R45T with a gap of .035. The plug for a 1975 is R44T with a gap of .060. The plug for a 1976 is R45T with a gap of .045. The plug for a 1977 is R45T with a gap of .045. My question is- being that I am using a HEI dist. what should I set the gap at, .060 or .045 The second question is should I go to a R44T plug. My third question is should I look at a better coil. I now have a stock HEI coil. Can you buy a High Perf. coil which will fit inside the top to the stock HEI dist. cap??

I have been purchasing spark plugs are a 71 Chevelle, when I should be buying plugs for a 1975 something. You have the book, but I thought that HEI where put in 1972 cars. Thanks for the information. I really overlooked the spark plugs application.
