spark plug wire length?
I bought a set of MSD wires for our car, they came all the same length and I have to cut them. No problem except I threw the old ones away some time ago. ( dumbass ) I don't cut wrong lengths and have to spend a **** load of money on new wires ( i think these were around a hundred ) so Im asking if anyone has an original set, an old set or just know what the sizes are as I haven't had much luck looking it up on the net.
We have a 350 and our car is a 79 if that helps. Thanks in advance

Depending on 'how' you run them, the length would be different. The best approach is to install the plug boots on the plugs and run them backwards to the distributor. Then, you can cut them to the length needed and install the distributor boots.

I have a points distributor and ran the wire through the boomerangs.
The 9508N set is cut a few inches longer than stock.
You have a HEI distributor so these stock measurements might only get you in the ball park.
1 - 2 - 3 = 49"
4 = 45"
5 - 6 = 32'
7 = 28"
8 = 26"
Coil = 10"
