Heads will be standard heads, not the E7s
Cam will be different, flat tappet regular cam and not the roller HO cam
Distributor drive gear to go with the cam
Different computer
So much less HP that the injectors will be smaller 14 LB/hr instead of the 19Lb/HR found on the mustang
regular cast pistons instead of the HO TRW forged.
I may be wrong (and probably am) but I thought the crown vic also got a smaller throttle body.
It looks like an HO motor with the intake flipped, but it is just a regular little 'ol 302 that has a basic speed density fuel injection on it. 160 HP if I recall (again probably off a little, maybe 180, 140?)
Nice little motor, but don't buy it as an HO, it isn't. If you just want a nice running, easy starting injected engine then this is a nice choice, get it. If installed as if it were in a crown vic, it will run like it was in a crown vic. Good engine.
If you are expecting an HO, this is not it. Not cost effective to convert to an HO either.
Back in '87 the (idiot) salesperson probably gave him the line "It has a Mustang engine in it" and opened the hood of a Mustang parked right next to it, they do liik the same. Any lie for a sale, even if the salesperson didn't know they were lying. The fuel injection stuff was new back then.
