71 H.O. spark plug wire terminations
So I ordered and received what are supposedly the correct dated spark plug wires for my 71 T/A. Two of the eight wires have a 90 degree termination at the distributor cap (the remaining 6 just have a straight termination). Can anyone confirm whether this is correct? Appears to be one short wire and one intermediate length wire. Any photos of the distributor/plug wiring on a 71 T/A that are stock is appreciated! Thanks for any help.

So I figured out the two wires with the 90 degree distributor terminations are the #7 and #2 wires, which are the two on the very front of the distributor. I guess that is to help prevent arcing from the wire to either the air cleaner base or the shaker base.
What is interesting to me at least is that my engine has suffered from occasional misfire under full throttle load (i.e. drag racing). I can only wonder if this is partially or fully being caused by the aforementioned arcing, as my current wires are a universal type which uses all 180 degree terminations at the distributor. Time will tell. I just don't recall ever seeing stock engines with this setup (two wires with 90 degree distributor terminations). I'll have to look for this in the future when I come across other restorations or stock engines (with original wires, what's the likelihood of that, huh!). |

I put my original spark plug wires somewhere. If I find them I’ll let you know what they are like.
