Spark Plug Wire Routing--1967 427 with K19 AIR

[Gary C.]

Hi All

Curious if the spark plug wires were inboard or outboard of the AIR tubes as installed at St. Louis. My car has them inboard as shown in the photo below.

The AIM does not specify, unless one considers no instruction to remove the wires to allow for instillation of the tubes to be instruction to leave them in place. Since there are no insrtuctions to that effect, I assume inboard is proper.

It just strikes me as odd that they would call for the wires to be in direct contact with the very hot AIR tubes. Any comments? What did they do when nonshielded spark plug wires were used? I could not find anything in my 67 AIM re the L88 and AIR

Thanks in Advance

As you noted, the AIM doesn't provide any guidance; however, the wires are the same with or without K-19, and the outboard routing appears more natural, as on non-K19 cars. The Dobbins book is usually a pretty good reference, and it has photos of an L-71/K-19 engine on page 264, which shows them outboard, as in the photo below.

You won't find anything about L-88 and A.I.R., as the '67 L-88 didn't have A.I.R.; that started in 1968.

These pictures may help. Most of the photos I have show the spark plug wires outboard on both banks. The K19 with C60 cars are a toss up.
