ok i'm sorry guys, i'm sure your tired of this question. i have a 99 dak with a 3.9l.
can i put a throttlebody from a v8 on my v6?
will i notice a difference in power. will the swap be a direct fit. throttle cables and all???

 

direct bolt in, except you need to reuse the tps from your old tb. expect a reduction in mpg for long trips, but an increse of mpg for shorter trips. I would only do it after an exhaust upgrade - my 3" works great, also you'll need to get an intake, the exhaust and larger tb won't be preforming at max with the stock airbox.
