I'm wondering if it would be possible to to a swap the motor from an older pre OBD2 truck into a newer OBD2 truck. The motor is from a '95 TBI and is a 5.7L small block, I want to try upgrading it and putting it into a '98 body with a 4L60-E (also going to be upgraded) transmission. I want to know if there was anything that I should watch out for, like if I would have to change any of the wires and computers, fuel routing, if I'm able to change it from TBI to Port-injected, and to put some other upgrades into the motor. My goal is just to make a fun mud bogger but I wanna make sure that I don't screw myself over and have it done properly. Any help and thoughts appreciated! Also I'm sorry if this is the wrong place to post this.

The easiest way is to use the TBI short block and the Vortec heads, intake, and accessory drive. Stick with the Vortec injection. Inspect Vortec heads carefully for cracks between the valves and spark plugs before installation.

With Vortec heads, the Vortec intake will bolt right on just like the original engine.

I didn't mention previously, but you'll also want to swap the cam over along with the roller lifters, spider assembly & dogbones, and cam retaining plate.

You'll also need the Vortec balancer, and reluctor off the front of the crank. You'll need a new timing cover because they're cheap plastic. The Vortec-specific timing cover has a boss for the crank position sensor.

You'll need the Vortec water pump.

Here's a thread with details.
