I read a 4bt was around 1100lbs fully kitted (without oil <img src="/forums/images/graemlins/smile.gif" alt="" />)


The 4D56T weighs about 400lbs, makes the same HP and is a balanced engine.

The 4D56T makes 104hp and 177ft lbs of torque.

The 4BT makes 105hp and 260ft lbs of torque.

While the 4BT makes a lot more torque, it's horsepower that gets you going down the road. Any benefit in torque you would see from the 4BT would be offset by its weight.

The other thing about the 4BT is the tranny and frame mods. While the 4bt weighs 700lbs more than the 4d56T, any tranny you add to the 4BT will undoubtedly add several hundred more pounds to your all ready bloated rig. Before you know it you have a 4300lb truck with just 105hp and 260ft lbs of torque. That would make for slow ride.
