    I'm brand new at this, just got my own 98 GT last weekend. I found a 68k miles 4.6 engine taken out of a 1993 Crown Vic with 68k miles for cheap locally. Does it have the PI head and intake I would use to up the horsepower on my 98 Mustang motor? For that matter, would I be better off just swapping the entire motor? I see a lot of posts about the non-PI and PI motors, but so much info my head is spinning...

    Thanks!

    Its tough when you first get started learning about the differences in modular engines. If I remember correctly, that crown vic has an engine very similar to yours. I think the heads might have some differences [MENTION=14727]96blak54[/MENTION] should be able to put some info in here. I don't think the crown vic got pi heads until early 2000's like 03 or so. If you are looking for a straight up swap to get you car running then this engine should work fine and bolt right in, but if you are looking to increase performance then you will do the same work to this one as you would to you 98's engine.

    ^ pretty much sumed it up

    The 93vic is a replacable engine option, but not in a performance aspect. Swapping to the pi package is a great performance upgrade! To simplify a pi swap , look for a set of heads from a 2004-up crownvic/lincoln or E-series van. These heads have more threads to keep the sparkplugs within unlike the pre-2003 pi heads that spit the plugs out.

    Their are a few scenario upgrades to consider. Just ask questions as you learn. We will be here to answer

    It will not have PI components, I believe the crown Vic's didn't get the PI heads cams and intake until 2001 (may be off a year). Mustangs got the Pi parts in 99. If the price is right though, it may be a good buy to have as a backup or to start a build with

    Thanks! I was only a decade off :). My wife's 98 and mine both are relatively low miles (under 70,000 each) and run great, so don't need it for a swap. It is on local craigslist with tranny for only $100. Too good to be true, right?

    The CV didn't get the PI motor until 2001. Even then they produced less hp/tq than the Mustang GT with the PI motor.
    The CV with the PI motor made 235hp @ 4750 276tq @ 4000.
    The PI Mustang makes 260hp @ 5250 rpm 302tq @ 4000 rpm

    Would the difference in power be due to different cams, exhaust system, compression, or a combination of all of them?

    That difference would probably be exhaust and intake plenum difference (manifold is the same). The cams, heads, pistons, are all the same.

    Not to mention the tune. Civilian vics/lincolns/merc's are geared up for interstate gas mileage. They even came equiped with knock sensors unlike any pre-04 mustang. The civilian panther platform could touch 35mpg on long tank draining interstate trips. The P71 panthers got the good tunes!
