Small motor in big truck = lots of noise and a slow trip to the dairy.
If your really keen though you want a Toyota T50 5 speed with a rare as hens teeth 4age bellhousing.
You will need custom drive shaft to fit the toyomotor box to the chuvit diff, custom mounts to fit the motor to the chassis.
And if you need advice on how to turbo a 4age, then thats a whole nother problem, suffice to say there are cheaper and more powerful alternatives.
