Hello to all. I have a quick question. I have a 1994 2500 GMC Burb with the 454 cid package. right now I have 7mm spark plug wires. I was thinking of stepping up to 8 mm or larger. I also plan on installing a Mallory Coil. Would this be a good combination for this beast. I am looking to SQUEEZE every bit of mileage from the truck.
Blessings to all who have read.
Thank you in advance
Chuck aka ulremember.
