Yea, a 350 was a sure good motor. As well as a 351w. If it aint broke, why fix it. I don't even know what my king ranch has in it. The big motor is all I know. Spark plug changein time was 1/2 a day by my old mecanic buddy from alabama. He cussed the truck then cussed me. 200 dollars. Labor. Yall must have them union machanics up there? They need to be beat with a oak limb. I got a old powerstroke. A 96. Its got over 400 thousand and will still pull a gooseneck load of hay.
