Great info from everyone, thanks very much. I really don`t intend to Hot Rod this truck. I doubt if it will even see dual exhaust, however thats not to say that I`m opposed to good `ol stump pullin, raw dog TORQUE! The most important thing to me, that will make it the most fun is 100% dependability. Start every time, never run hot, and I`m happy. I think that with the stuff I`m learning on here from you guys, I can choose the right rear end, and trans, and be able to "putt" around town, and drive 70 down the hiway. That said, has anyone had any overheating problems with 261 siameased cyls? (provided steam holes are drilled in the head your using) JD
