they are really not interchange able because the truck has a vgrove belt and the 240 is a multigrove belt.but the timing marks should be the same. but it kinda depends if they are right on the pulley its self if its aftermarket then who knows if its even right.

yes, the timing marks are the same. Depending on the year of your truck though the base timing isn't going to change much because it is controlled by the ecu. What is the goal by changing the timing away from stock?

i'm not sure how the marks can get off on a ka pulley? i know on the VG pulley you can disassemble the pulley and reinstall the portion with the timing marks incorrectly, but if memory serves, the KA pulley is one piece? at least i'm pretty sure it is on my 97. according to the FSM the marks on a 96 and 97 are 5 atdc, tdc, 5 btdc, 10 btdc, 15 btdc, 20 btdc.

The reason why I ask is I'm wanting to run under drive pulleys off a 240 since there "the same motor"
