[Ski-me]

Engine swap is a super expensive, time consuming option. I would drop the lift to 2.5" and then if absolutely necessary, drop the tire size to 31" or 32". Otherwise, I'd just drive it as is.

If it was me, I like the look of 33" tires with a 2.5" lift vs. a 4" lift. I personally think the 4" looks too high for me.

This does look like a 1/2 ton truck (6 lug wheels), so should have the 4 speed OD, 700R4 tranny.
