I purchased an MSD 8.5mm wire set to replace the aging set of wires currently installed.
I started up the engine and ran it for a minute to make sure it started up okay. Tomorrow I will go for a drive and see if that helped.
I also repalced the 14"x3" round Holley air cleaner assembly with an Edelbrock pro-flo 1002. It is alot more companct. It was much easier to route the plug wires as a result of changing air cleaner assemblies.
