Correct plug wire legth install

[CGASTON]

I can't remember and seem not to find it anywhere, the correct location and length of wires when doing a new wire install. Anyone know this or where it is located? Thanks!

I can't help with the "length", but I know Kirban Performance sells a really nice plug wire set that is OEM length. I run them on my car.

I have seen that. I was hoping to find something that says "Longest plug wire or 10" plug wire goes to #1, then 11" goes to #4"..... No worries though.

Although my car is put away in storage (an hour away)....I do have a set of brand new ATR plug wires that i bought from Dennis Kirban. They are in my garage....I can dig them out this afternoon and measure each of the six for you if you like.

I've measured up the spark plug wires....these are from a box of new ATR plug wires.
Measurements are OAL (from end of spark plug boot to centre line of coil plug).

2 x 24" OAL
2 x 25" OAL
1 x 27.5" OAL
1 x 30.5" OAL

Unfortunately the spark plug wireset is not numbered.
By looking at the drivers & passenger spark plug wire diagram I listed above, my best guess is that the longest wire would be to #1 @ 30.5" , #6 @ 27.5" , #2 & #5 @ 25" , and #3 & #4 @ 24".
