Re: Sy #260 Homecoming
Sweet looking truck.
Like everyone said,get it running right stock before you do anything.
I would bet that it has the wrong plugs in it right now,which would SEVERLY hamper it's performance.
If it was mine,I would replace the dist cap,rotor button,plugs and plug wires.Check to make sure that the timing is set at 0 with the tan wire disconnected.Make sure the IC pump is working.Adjust the TV cable to make sure it's right.Check for vacuum leaks.
