My 3.0 cost:
$1500 Taurus block (date of Ford prod Jan 2001), with "prep"
$250 63mm TB
$250 Y-pipe
$250 shipping for all the above
$900 Quaife (NOW $600

)
$250 misc. BAT and shiping
$60 K&N
$300 (or so) from Mass.
$600 Bassani
$700 MTX-75 work (more than just quaife install - includes machine shop)
$150 oil pan baffle (and shipping)
So that's, uh, a lot. $5200 PLUS install labor. Drop $300 on Quaife price. A bit over $6k all told, but not far and a few things that can be deleted.

Whoa! I was really only kidding, but I better change my sig to something more believable.
