I`m taking it as this is a DIS ingnition system
on a vin T it shows the firing order from top of ing coil is
145263 but it also shows another firing order of 143652
that might be for a 2.8
Hope this helps

I can answer this question...
I need the firing order on spark plug wires for a 92 chevy caprice?
