wayneman Posted December 2, 2011 Share Posted December 2, 2011 This is sort of a stupid question, but if you don't know, you just don't know. I was getting ready to drill my holes for my plug wires and it just didn't look right. I began to do some online research in reference to where the plug wires went on the 67 Charger and it looks like they go into the top of the valve cover. When i pulled the valve covers out of the green bath (taking off the Chrome) they appear to be made for this arrangement. Is this an arrangement for individual ignition modules. If I run the wires into the top of the valve covers - will I be right. Thanks for all the help in the past and future. Obviously, auto shop was not available to me Also, does anyone know of a model club near Raleigh NC ? None listed in the section.

a/gass Posted December 2, 2011 Share Posted December 2, 2011 yes the spark plug wires go in the top of valve cover on all early hemi's. Quote Link to comment Share on other sites More sharing options...
SuperStockAndy Posted December 2, 2011 Share Posted December 2, 2011 Yup, any engine with spark plug wires going through the valves covers is a Hemi. since the combustion chamber is a hemispherical design, the spark plus is in the middle.

Roadkill2525 Posted December 2, 2011 Share Posted December 2, 2011 By your definition of a Hemi that makes pretty much most import twin cam heads Hemi's too. Quote Link to comment Share on other sites More sharing options...
whale392 Posted December 2, 2011 Share Posted December 2, 2011 (edited) If the Charger engine in question has very wide valve covers, it is a Hemi engine and the plug wired do go through the center of the cover. Since the 67 Charger model wasn't issued with the 440 wedge, I would say that is what you have. Andy, might I suggest you narrow your field of answer. Not all engines with plugs going through their valve covers are Hemi headed. Look at the modern DOHC set-ups. Are they Hemi? By your words, they are. But they aren't.......they are what is called a Pentroof design. Basically two wedge configurations placed back-to-back with the plug in the middle. The Honda D-series engines aren't Hemi either, and their plugs go into the cover. Their B and H series motors are also straight-through the cover, but are DOHC Pentroof heads.

I read about that a while ago and then I forgot about it, not a very popular head design... Quote Link to comment Share on other sites More sharing options...
whale392 Posted December 2, 2011 Share Posted December 2, 2011 (edited) Andy, hate to break this to you, but you need to go back and read. ALL current DOHC designs are based on the Pentroof head. Didn't work well my tail, it works fantastic. It combines the best aspects of a wedge and Hemi head. Perhaps, when you are older and wiser, you will learn to keep quiet until you really KNOW what you are talking about. You just made yourself look foolish; please go back and edit your reply.

I made a mistake, why am I suddenly the jerk now? If you look back at my first post, Yup, any engine with spark plug wires going through the valves covers is a Hemi. since the combustion chamber is a hemispherical design, the spark plus is in the middle. See what I did there? I made it CLEAR that I didn't say that if the plugs are in the middle it's automatically a Hemi. I'll be honest, I don't know a whole lot about most engines other than domestic ones. I do, however, know a fair amount about the other parts. Edited December 2, 2011 by Andy C.

whale392 Posted December 2, 2011 Share Posted December 2, 2011 Andy, you are what, 14? You wanted to come off like you knew what I was talking about and sound like you actually know something. That is what is called a fake, a posuer. If you don't know, keep quiet. You tried with the Hemi thing..........but you epic failed with the Pentroof.

You tried with the Hemi thing..........but you epic failed with the Pentroof. I'm 13. I don't know what the big deal is, and when you said pentroof I DID know what you were talking about!!!! I did a bunch of studying on engines a couple years ago, but I've forgotten some of it. Sorry Wayne for this being completely off topic. I had no intentions of people coming in and screwing with me and completely changing the topic. Edited December 2, 2011 by Andy C. Quote Link to comment Share on other sites More sharing options...
whale392 Posted December 2, 2011 Share Posted December 2, 2011 (edited) Andy, you said, 'Any engine with the spark plug wire through the valve covers is a Hemi' YOUR WORDS. Get it right or SHUT UP. Not all heads with plugs through the valve covers are HEMIS. God are you dense. You want a real schooling, we can take this to PM.

whale392 Posted December 2, 2011 Share Posted December 2, 2011 I was building these engines before you were born Andy. So I think I know a thing or two beyond 'reading' it. Quote Link to comment Share on other sites More sharing options...
Jantrix Posted December 2, 2011 Share Posted December 2, 2011 Excuse me Mr. Moderator! We need a clean up on aisle three. Brad, he's a kid. Cut him some slack. I got one that will shoot his mouth off about anything he's heard two facts about. I've tried to break him of the habit by "schooling him" as you put it but it just doesn't take.

whale392 Posted December 2, 2011 Share Posted December 2, 2011 We took it to PM, Rob. Hopefully, he will get what I was trying to tell him with my first reply to him, before he persisted with the 'You misread me' stuff. That is why I left this thread. Still, if he wants to 'spit fact', he had best have an idea of what he is talking about, because he just made himself look foolish here.

Chuck Most Posted December 2, 2011 Share Posted December 2, 2011 Wayne, I'm assuming you are working with the Revell kit? If so, it is a Hemi. This is NOT a factory stock Hemi, but your wiring should look something like this: Quote Link to comment Share on other sites More sharing options...
wayneman Posted December 2, 2011 Author Share Posted December 2, 2011 Thanks everybody. Chuck - That is just what I was trying to find. That photo clears it up. Actually, I think that I will do the engine in those colors. I was going to Alclad the valve covers, but the black looks tough. Thanks.

wayneman Posted December 2, 2011 Author Share Posted December 2, 2011 Further study of the photograph saved a nasty little mistake. I was about to put the dipstick on the wrong side of the engine. Thanks again. Wayne Quote Link to comment Share on other sites More sharing options...
Chuck Most Posted December 3, 2011 Share Posted December 3, 2011 Those black valve covers were actually stock. Which is fine with me- I think they look way better than chrome. Quote Link to comment Share on other sites More sharing options...

62rebel Posted December 4, 2011 Share Posted December 4, 2011 and, if i can add something missed in the replies to the original question: no, the Chrysler Hemi doesn't use individual coils for each spark plug as is done in many modern cars. those are rubber boots to seal the openings, and simply extend down to the plug through tubes. i suppose, though, that some manufacturer probably does make a system like that today, just not as a stock item. many engines share the hemispherical combustion chamber design, but only Chrysler owns the right to the name "Hemi" for it, or at least they did for a very long time.
