Im gonna say it is a 4.0 OHV which came in trucks 1990-2000
I believe the 2.9 was replaced by the 4.0 not 100% sure

Some specs for the 4.0 OHV

Nitrous Oxide Systems (NOS):

Nitrous Oxide Systems (NOS) showed the world how to effectively harness the power of nitrous oxide for automotive use in the 1970's. Since then, NOS has powered more racers than any other brand of nitrous. When you're looking to go fast, rely on NOS to deliver the most power per dollar available. From stock engines to race vehicles, jet skis to trucks, NOS has a kit for you.

Modifications:

Head Porting:

Port your upper and lower intake. The intakes don't line up diameter to diameter. Porting opens this up and allows better flow. Knife edge the intake side of the throttle body to remove the front lip. You can use a Dremel tool to grind, sand and buff this area to obtain a smooth airflow in to the engine. You can also mill down the butterfly to blend in to the shaft for a smoother air flow.

Ignition:

MSD - Manufactures a DIS ignition system along with wiring harnesses. Find their parts at Summit Racing.

JetChip - Makes a module to reprogram the engines computer. Click HERE.

Im not sure where any numbers would be on the engine

Most times there is a vin number attached to the engine it's self if you find one you can track it back that way as long as he didnt remove it
