mustang 302 vs crown vic/f-150 302?

[poison_ivey]

i looking into getting a crown victoria instead of a mustang, like i thought i would 3 mths ago.(dont weep for me). i thinking family car sleeper . but first, i need to get about 325+ hp just to run mid 14's. first, i need to make the 5.0 in the cv the same as the one in the stang. ne1 knows about the different 5.0's? b/c i figure i need to get my engine identicle to the stangs before i do basic mods like intake/exaust.
please help. i might post this in the cv forum too...

First of all, dont bother making the stock engine "like" a Mustang's 5.0 HO. The Vic will have a standard 302 with cast pistons and the old firing order. It will probably have speed density instead of mass-air metering too. If you need all that power just to break a 14, then I would either get a 351W, blower, or a lighter car. The 351W will look alot like a 302, but the potential is greater. Then again, a 460 will set you up even better. The swap will get a little more involved, but jeez, 500hp with no sweat.

If you really want a 5.0 HO, you'll have to change the throttle body, cam, upper and lower intakes, pistons(HO had forged '87-92), computer, and possibly the heads and injectors. It would be more economical to just get an HO out of a Mustang or Lincoln.

o i c
i didnt know the mustang had the 5.0 h.0. interesting
maybe i will get lucky and find a 351 or a 5.0. H.O.

if you're a regular on this forum, you'll notice i have a thing for 351s. keep in mind that it can be difficult - emphasis on can be- to find parts. especially if you have a Cleaveland. in my own opinion, the Windsor is the way to go. same firing order and cam as a 302 HO, plus many of the same external parts. same heads, even. bear in mind that if you go this route, a computer replacement will be in order, as well as wiring, intake, and all sorts of things. if you wanna make a bunch of power, then either go with nitrous or a blower or even a big turbo, set up such that you can run pump gas. and, last but not least, and i CANNOT emphasize this enough, DO YOUR HOMEWORK. i know nothing about valve trains, but i have a friend who builds these motors all the time (and words for Ford =D) who will help me figure out my set-up. i dont' wanna see anyone put a motor together at great expense, only to find that it doesn't work the way they wanted it to.

nothing wrong with making a Crown Vic 302 "like" a 302HO. Only thing that sucks is its a non roller motor. But that is easily fixable.


I use a Crown Vic 302 block in my mustang.

no roller motor?

[StangNut86]

no roller motor = flat-tappet lifters. flat-tappets = friction. you wanna upgrade that bad boy to hydraulic (or solid, if you're going high RPM) roller lifters/cam. keep in mind that the cam must be biased based on your lifters. also, your induction system (forced or n/a) plays a major role in your cam bias.

keep in mind i'm still a kid in high school and i make 500 a month
*edit*
i forgot to also say that i dont have milions of dollars to pour into this engine. so new 5.0L is out of the question. yes, i do want to make the engine like the h.o. i asked this b4, but i didnt get an ans. basicly, i need
A) 351W/5.0l H.O. cam to change firing order(can order one/get one from junk yard)
B) 5.0LH.O. comp... again, i had plans to buy one. will the engine still be driveable w/ the h.o. cam? or will that have to be all at once?
C) yall said pistons, but i probably wont get that...
D) i planned on replacing everything from the airfilter up to the intake maniflold....
E)exuast gonna go too... gonna get some nice ones.

so, its the same block, but less powerful rite?

damn, i changed my mind about cars 2much... but this time, i gonna start looking, and hopefully, i will be a proud owner of a lincoln/ford/mercury fullbody car
just hope that my dad wont be gay all of a sudden....

A) You have to get the lifters, lifter dogbones, and the lifter spider too. Dont get a cam out of a pre-'94 351W because it will be a flat tappet
truck cam. '94 and later is just a roller truck cam.

B)The HO cam isnt very knarly so it shoudlnt bother a speed density sytem. In fact, the early '87 SD Mustangs had a more agressive cam than later mass air cars.

C) Forged pistons. You dont need them unless you plan a power adder or nitrous.

D) Then you'll need all those parts off an HO Mustang or Lincoln.

Yes, the standard 302 has the same block, crank, rods, and maybe heads as the HO, but thats it. The regular was rated at something like 150hp while the HO was 225hp/300tq.
