Hey guys! I tryed searching if anyone is using E3 plugs with their aftermarket aluminum flathead heads. I might be dumb and not worded it right. I have a set of 1948 Weiand Full Race aluminum heads on my flathead and was trying to find info on if anyone had used E3 plugs. They say they put out a faster spark. I live in an elevation of a mile high and want to get the best spark possible plug wise.
I was wondering where you found this information and what brand name of plug it's referring to. I found an old spark plug conversion chart. It looks like Blue Crown offered an E4 (cold) to E9 (hot) but none of the other brands showed anything close.
The brand is E3 diamond fire. There were tests on horsepower tv and speed channel, and the plugs out performed just about all the plugs on the market power and burned more fuel in the combustion chamber. I was qurious if any flatheads were running them.
I am just hoping to find a flatty that is running them so I can see if they are better than the common copper plugs. They say you dont ever have to mess with the gap since the gap is set by the 3 posts attached to the diamond shaped plate.
The plugs in my daughters Volvo are the same as E-3's...and the porcelain is labled "Volvo". Not trying to steal a Thread, but I wonder if they would be good with a 60,000 volt coil...
I figure if they can handle a msd ignition like some guys are running i'm sure a 60,000 volt coil will do no harm but make a stout spark!
I just know that flatheads are finniky and there are guys that try just about anything. Hell thats just what they did back in the day when flatheads were winning all the records at bonnivile.
Try a set of NGK B6L set to .030 When I put in Champions the motor ****ped out at 3200. With the NGKs it runs right up to 4800 and still climbing slowly.
Thanks Don! Im trying to get as much info possible that works on those hot little flatheads. My elevation is a mile high and I want to get the best performance with this great old mill. I like to drive them more than repair them.
Multiple spark discharge. if you want the best burn possible, run an MSD. the plugs are only part of the equation, and you can try different ones after your car is on the road easy enough. If you have a well set up MSD igntion and correctly gapped plugs, I doubt you could tell the difference between plug brands.
Your right Thunderbirdesq! Im gona head down to the parts store tommorow and get a set and try them out. If they are as good as the tests on the speed channel say we might have another great flathead standard. Wish me luck! I am going to go on their website to find the right thread size & leingth & heat range tonight. Wont hurt anything but tha pocket book. LOL!
They do not list any plugs for the Ford flathead. I even tried to cross reference the plug numbers from different know manufactures, no luck...
I wanted to put E3's in my new Oddy SBC because E3 claims more horse on the dyno (as seen on Horsepower TV). WRONG! Don't believe everything you read or see. Oddy's dyno'ed E3's and there was NO difference what so ever. Billy Leverentz of Oddy's said "do you really think that E3 is going to pay to have their plugs put in an engine for adverti*****t to show that they don't do anything different other then cost a lot more money" I have been using NGK's ever since!
I am starting to find out why no body with a flatty has not ran e3's yet. There is not a cataloged compatible plug. I e-mailed their tech dept. to see if they might know of any compatibility. We will see. I will keep you in the loop if i find out anything.
Correct me if I am wrong,but I believe that Flatheads came with a 3/8 reach plug. No engines for some time have been made to use a 3/8 plug at least for cars, in some time. So you probably will not find an E3 plug made in 3/8 reach. The good news is that aluminum head makers knowing that aluminum is weaker that cast iron made the heads thicker so that they would have 1/2 or 3/4 reach plugs for full thread engagement. Lots of guys don't seem to be able to get their heads around that. Look and see how long is a proper plug for your head. Go to the store and find a plug that has the correct reach for your heads. If E3s even come with a heat range choice get one 2 or 3 ranges hotter that median.
This is an ad from the inside cover of the March 1955 issue of Hot Rod magazine...multiple electrodes aren't anything new, and they still haven't really caught on in the mainstream.
I was informed from E3 that unfortunatly there is no equivalent to the NGK's or the Champion H10. Looks like im going to stick with the NGK's. That ****s! I was hoping to play with something new.
I've always thought that electricity takes the path of least resistance. If one ground electrode is closer than the others, then they won't be used, until they are the closest to the firing center electrode! HemiDeuce.
I talked to a few gentalmen that have been around the block a time or two and the told me to try a BOSCH plug that was used with "I know a Volkswagen Beetle". The Bosch W8AC for street and W7AC for race. My Weiand heads are a little thicker than stock and the 1/2 reach works great a with indexing washer. I went down to the autoparts store and picked them up and ordered the indexing shims from Summit. Before I put them in I gaped them at .03 and put some anticeze on them and took the jalopy for a spin. It seems like more pep than the NGK. My elevation is right at at a mile but they probly work at diffrent elevation with diffrent gap. Who knew. If you think about it a bug motor is a hot running industrial air cooled motor and a flathead isn't the coolest motor on the block. They made a diffrance for me, but its up to you to see what works best on your motor. And bottom line, the BOSCH is a lot cheaper than the E3 for a V8.
