NOS AC Delco SS550 ORANGE race spark plug wires 7mm stainless BULK SPOOL roll
 

Hi Gang,

SUPER RARE treat available today.

This is a partial roll of original Delco SS550 / SS-550 7mm stainless bulk HiPo RACE spark plug / ignition wire.

This is the correct, old school version of these wires / this wire as evidenced by the font of "DELCO" and that they are UNDATED.

This is what you want for a truly original "DAY 2" look; this is what was available when these cars were still new. L88

Again, this is a partial (originally 100') roll and there was likely one set of wires made from it back in the day. I don't want to unroll the spool as the wire is original and intact.

So, Mrs. Anthony knows math and told me a formula to use to estimate total length:

2ΠrxNxD

r = radius of roll
N = number of loops per length
D = number of layers of loops

I'm calculating 20 loops on the roll and 6 separate layers of loops even though it looks like there's seven on the spool, to be conservative and err on the low side:

And I'm rounding pi to 3.14 of course, and varying the radius for each layer of loop rather than keep that constant, so:

2x3.14x.75"x20 = 94.2"
2x3.14x1.00"x20 = 125.6"
2x3.14x1.25"x20 = 157.0"
2x3.14x1.50"x20 = 188.4"
2x3.14x1.75"x20 = 219.8"
2x3.14x2.00"x20 = 251.2"

= 1036.20" / 12 = 86.35'

The above is an (educated) ESTIMATE, but I will bet there's at least 80' on this roll and will warrant that number.

Enough to do at least three BBC cars conservatively and maybe even four motors, especially if you're doing a SBC engine as well.

$1000 PPG shipped in the US.

Cheers all,
Anthony

Gooooood stuff Anthony! This is a good deal. I won’t tell you what I paid for my YENKO Deuce SS550 wires! :blush: GLWS!

Hey Friends, I'm getting some interest in just enough for one car from several members here.

I'll unroll it later today and measure it all up and reply in order to PMs.

Cheers all,
Anthony

Hi Gang, I unrolled it all and it's just over 90' total!

Not sure what they did to just use less than 10' of it, but there you go.

So, I'm cutting it into about 30' rolls - that is plenty for any configuration of motor IMHO with a generous contingency for trimming and wastage.

Note that some markings have transferred while coiled up for 50+ years...

All PMs & texts replied to.

Cheers all,
Anthony

Hi again everyone, just over 30’ left. Same $12.50 per foot.

$375 PPG shipped.

Cheers all,
Anthony

Count me in for the last 30.

PM going out

I think I have some of this on a roll too. I may need to look for it.

^ Hah, before you do that Jon...

I wanted to let everyone know #2 buyer fell through and I still have 30' left. He's keeping his car Day 1 after all.

Bruce & Tim, wire shipping in the am. Cheers all.

Hey Gang, last 30' roll is now sold too. That's all of it. Thanks friends.

Hopefully Jon can help out now!

Cheers and Happy 4th!
Anthony
