whats a termi motor? An NO its a 3.9, 1/2 way thru 2004 ford changed to a 3.9. Dunno why just is what Ive read! i'll have around $5000 to spend. Id rather spend less if possible. have considered 4.6 3v, 289, 302 or 351w swaps, s/c, turbo, just bolt ons. but i dunno in reality how much all that will really cost
