AP4. They are relatively cheap auto cannons with D3 shots. Its hard to go wrong with lootas for long range fire support.
As for
OP you should think about what general strategy you want for your Orks. Trukk lists will need lots of trukks with things to put into them (boyz, meganobz, tankbustas, burnas, etc). Battlewagons (and the blitz brigade formation) are a fairly effective tactic of getting your Orks down field in relatively one piece. Warbikers are a solid choice for mobile units with good shooting (for Orks), good survivability, and are decently good in close combat. As others have said Mek Guns (kannons, lobbas, kustom mega kannon) are very useful weapons and give some long range fire support to your army to soften up the enemy before you charge in. Being artillery and crewed by grots they have T7 and yet each crew is only 3 points each so they have insanely high durability for the cost. Lootas are a bread and butter unit that can handle your
AA and anti light/medium vehicle killing. In any list though you want Tankbustas as these are probably the best unit in the Ork codex by a wide margin. Cheap
Str 8
AP 3 shooting with tankhunter and they have melta bombs so charging even super heavy vehicles usually means your going to be murdering that vehicle. Grots are a non flashy but very effective unit for capturing objectives, blocking units, and drawing fire. You really want a Warboss either on a bike or with mega armor to make use of the lucky stikk.
