Best Spark Plug Wires for 1977 Suburban

I've been perfectly happy with MSD 8.5's on my last truck. It gave it a noticeable improvement in driveability.

I put Taylor ThunderVolt 50's on my new truck, and I had two of them break on me when removing them to diagnose a LOSS of performance after the install.

Granted Taylor says I can return the two wires for good ones, it's a bit of a pain in the neck. They said those two wire were causing the loss in performance.

No problem,

Mine were all pre-built and ready to go... It's on a LS1 based motor with the individual coil packs sitting on the valve covers, so it's only a short 8" wire down to the plugs.

I think I'd be surprised if either of these companies DIDN'T make a pre-built set for your motor.

I paid about $50 for the MSD's, and $68 for the Taylors.
