The 350 in my '84 GMC just isn't hacking it when I haul my large overhead camper and Jeep on a flatbed trailer. I want to replace it with a 454. I'm willing to take a smoker and rebuild it. If you want to sell the entire pickup, I'll consider that as well. Home phone: 719-548-9569 Work phone: 719-556-7858 Email: email@example.com Thanks Dave.
