67 BB shielded Ignition wires

[Stephen L.]

Does anyone have a photo of a known set of ORIGINAL "67 BB with radio" ignition wires showing the ends????

I have found, in my stash of old Corvette stuff, what I believe to be the original wires from my 67 BB. Back in 1982 I removed the wires from the shielding and installed new wiring in the original shielding as the wiring had very high resistance.

These original wires are stamped "H PACKARD TV R SUPPRESSION 1-Q-67" as shown in the photos.

The wires have "straight" connectors at the distributor cap end.
They are black wire with a dark grey boot.
6 of the wires have the small angle connector at the spark plug end; however 1 wire has a right angle connector. (I am missing 1 wire).
This wire (RT ANGLE BOOT) is also the shortest one. I assume this one would go one the #7 cylinder. Possibly the missing one is similiar and would be used on #8 Cylinder.

QUESTIONS:
Is the right angle connector for cylinder #7 & #8 correct?
Are the straight connectors at the DISTRIBUTOR cap correct?

I see nobody with original '67 BB & U69 wires has jumped in, allow me to give my 25K ohms' worth.

Pic is of a GM service set, dated 2Q87, but I believe it correctly represents the boots for all cylinders for all Mark IV braided wire motors. Your straight distributor end boots would be correct for no-radio Corvettes; no exceptions for certain cylinders, IMHO.

Are you saying that even the wire with the 90 degree plug boot is dated 1Q67 ?

Check Noland's Vol.2, pg 304, where he shows GM dwg for braided #2 plug wire (this dwg shows the plug barrel clips, so technically it's for '65-6 BB's, although the '67 service P&A30 shows same # for '65 thru 7).

I don't have a '67 AIM, but the '65 version shows different part #'s for each U69 plug wire, which I imagine means that in production, the wires were each of a different length. The '67 parts book has consolidated those into 3 lengths; cyl's 1, 2, 3, 4 have same #2989417 as shown in Noland's book, at 34"; cyl's 5, 6, 7 are 25", and cyl #8 is 20.5" [also same as in '65 P&A30]. By 1970, the parts book consolidates those further to 2 numbers with lengths 34" and 25".

The '65 TIM&JG says "current replacement Delco wire sets have shorter boots" without going into specifics, so I don't know how my pic would be classified. Straight distributor boots would not clear the distributor chrome cover, I believe.

Wayne,

The wire with the right angle boot has 1 Q 67 on it also.

I have a set of GM 3Q88 wires and they have the right angle distributor boots. They also are high resistance and caused a miss in the engine. I reinstalled the wires I made up back in 82 and the miss went away.

The original shielding shows its wear so now I'm trying to collect the parts to make a good set of wires. (I purchased a set of the date coded aftermarket stuff about a month ago.... Shielding a bit off and high resistance... not going to use 'em)

I've located some Packard 440 wire. Using my original boots. Purchasing some clips for both ends. Getting a date stamp made. My only question is should I reuse the right angle plug boot on cylinder 7 or 8 or both or neither?

The 67 BB AIM also calls out 8 distinct part numbers for the wires with U69 so they must have some differences.
The AIM also calls out 8 distinct part numbers (but different) for a non U69 car.

NOLAN ADAMS says braided wires were used on non U69 cars to minimize disturbances to other car radios, so why are there 2 sets of part numbers in the AIM???

The straight distributor boots were originally on my car. They were bent over sharply... probably why things were changed to RT Angle in the service replacements.

Are we having fun or what........
