Could be a t100, doubt it, prob a stupid owner who doesnt know what they have, or a motor swap

Thats a 3rd generation extra cab. Just as you stated, I would guess it is a motor swap or a 3.0 and the owners an idiot.


Edit: On second thought I highly doubt thats a motor swap because the ad states the heat,a/c, and cruise control all work. The 3.4 uses positive pulse rpm readings and the 3.0 uses negative pulse to power these options.
