Glowing headers

Melting Slicks
ok, lets get back to the basics...is the distributor in right? can you post pics here so we can all pitch in and help you figure it out....we need to make sure fuel, timing etc is right
glowing headers can be both from a lean or a rich condition, but what concerns me is one cylinder showing the glow...I am thinking maybe a lean condition coupled with retarded timing..(basing this just on what we know so far)

please post pictures,,,,I am curious on the physical position of the distributor....and how it was installed...take pic of top of intake, showing dist cap etc....I am betting/hoping we are looking at a tuning problem, timing, fuel etc and not a damaged/burnt valve however what the other forum member posted could indeed be the issue, valve adjustment, burnt/damaged valve....

Plug wires switched? Perhaps 5 and 7? I had a Ford 289 that did the same thing when I first fired it up. We held it at 2000 rpm to break in the cam but had to shut it down to fix the problem. One cylinder was red hot on the header. Double checking that the wires were on the correct plugs fixed it. Just my $0.02

likely no damage...lets get some pics going....pics of plugs, etc etc, top of motor showing distributor position, also check your cap, rotor, wires....have am ohm gauge? lets start with the basics, as I am betting that is where the issue is....then on to compression and or checking valve adustment.. all are valid posts from other members

I believe you've got the plugs all wrong on the distributor. The reason the firing order was mentioned was b/c that's the sequence the plugs should follow on the distributor. As I see it, you have the #1 wire in the correct spot, and I THINK you go clockwise from there to 8-4-3-6-5-7-2, but don't quote me on that, and I don't have a book close by to verify.

So are the cylinders numbered as i drew it?
My distributor has numbers on it where the leads go and it is numbered as i drew it, looking at it from above facing the way you sit.

Check where the wires actually lead to instead of what numbers somebody scribled on there. They are not connected like they are marked!

unless you have a "Corrected " distributor cap ...is it a standard cap, or a corrected cap? is it marked on the cap for plug positions? if its a "corrected " cap, odd /even numbers are on seperate sides......do you have a vacuum gauge? connect to manifold and it will tell you if you have a valve issue on #7 cylinder...this is an excellent site and will explain the readings http://www.secondchancegarage.com/public/186.cfm.. look at scenario #5

Brady..did you see the PM I sent you? lets confirm that the distributor is in right...set the motor up on number one, compression stroke, pop the cap off...make sure things are right.

Looking at your pics, it looks like all of the wires on the passenger side of the distributor are going to the passenger side of the engine and all wires on the drivers side if the dist. are going to the drivers side of the engine. Call me crazy, but that just can't be right. Or did they come up with something new that I'm not aware of ????????

I would possibly richen it..I personally run AC plugs....which is what they also ran in Apollo 11
Have you set it up on number 1 yet? check the timing mark then remove cap to ensure rotor is pointing to number 1? do this when you can, we need to make sure you are set up right...will only take you a half hour or so...
