OOoops, I forgot that if you change the wires, I would use MSD Red Wires. They are the best as far as I am concerned and many racers also agree. I have them on my full size Chevy Pick up and love them. They have the least resistance per foot than any other wire. I have a new set coming from Summit Racing for my new engine thats going in the pick up. I'm putting in a rebuilt 250 inline six, bored .0040 over that has about 15-20 more hp than the 350. It will be better on fuel and leaves lots of room under the hood. I love the ole' Chevy/GMC inlines. Nothing like them except the ole' International inlines. Henry
