Outdated Dansworth 1500 Powertrain Mod 1.3

Much much improved transmission for the gasoline school bus. (supporting agression factor)
Haven't added propane for gasoline bus yet, will be in next update.

Adds the Ford triton V8
Torque curve and coding supplied by
@Capkirk
With a modified Gavril 6-Speed Automatic transmission as it's only option.
Quite slow and when you do need the power you can floor it.
Superchargers are optional

Adds these:
9A=Same as 7spd but with 2 over drive gears (ive lost count on how many overdrive gears we have now )
4A=Heavy duty variant has a bigger T/C and powerful lockup clutch.

Dirty Radiator=Overheats quite easily
Normal Radiator=Realistic? Less overpowered than original
High Performance Radiator=For drag configs (has thermostat wide open).
