Glider kit config for 3406e

Hi,
Im in the process of securing a glider truck with 3406e engine and 18 speed. The ratio is set to 3.42. Cannot change ratio.
I need an advise of the hp and torque. The engine I selected is 2ws.18 speed 2050 torque tranny and 2050 torque clutch.
what setting should I ask the dealer :
550 HP with 2050 torque
or 600 HP with 2050 torque
or
550 HP with 1850 torque.

I also have the option to select 1ws or 5ek engines.

I live in the west coast. Most of my driving will be 11 western states and texas,KS,MO,NE.,OK
Loads will be heavy about 80 percent of the time. I will be pulling a dry van.
Please advise.

Thanks
Josh

 

California to OR , WA, UT, NV at times MT/ID/Co and back .

 

I know they are illegal in California . I will get plates from out of state , AZ or TX. I might park out of state and come back home in a car. I just dont like the def and Dpf trucks. too many problems. the repairs on these def trucks empty ones pockets real fast. I dont want to go shop for repairs all the time.
