just saw you didn't want to touch the rear gears, i'd seriously re-think that. its not that tough to find a used center section. i'd do that before a cam/intake/carb and headers  just my .02   

Its just tough to take a lil low compression 302 in a 4500 lb car with 2.79 gears and get it do anything that resembles pep imo

I used a slightly smaller summit cam in a 351w pickup i had, it was fine. summit cams are made by crane I believe.  best thing you can do to pep that bird up is a gear change. if you put a cam in it, then you'll need to put a stall in even if they say you can run a stocker. if you don't run 75 on the hwy all the time, throw a set of 3.50 (3.55's if yours has the 8" rear) gears in that bird. then when you put that cam in, put a 2200 stall or so in it and that lil 302 will wake up as much as its gonna wake up.
 
You must have used this one.
 
 
Did it have much of a "lope" at idle?  Did you put a stall in it?
 
Thanks for your input!

I seem to recall it was around a .447 in/.458 ex cam I used. I ran single exhaust in the truck so hard to tell any idle difference. in a windsor headed motor I don't think you'll notice much difference in lope until you get above .525 or so and start to get into the longer duration cams. Seems with the cleveland heads, smaller cams just sound to have much more lope to them over the smaller port windsor heads. At least thats what I have noticed and a larger motor will sound milder wit hthe same size cam, so it may sound different in a 302. i had 2.79 gears in that truck with stock stall, it was no faster off the line then it was stock, maybe even a hair slower. Once up to hwy speeds it was a little bit better then stock. Not a huge difference either way.

Okay, let's hear it for a 3.50 center chunk!!!!
Better intake and a 4bbl carb!!!!
Dual exhaust and ditch the cats since they are 40 years old and probably plugged up anyway.
Smog pump goes away, EGR??? We don't need no steenkin' EGR!!!
More cam won't hurt either.
 
Crown vics 86-91 have a roller 5.0 with flat top pistons and actually have slightly higher compression than the mustang 5.0, and the H.O. cam or an E303 fits right in. E6 heads so keep lift under .500
The above post should be read in a "Grumpy Old Man" voice.

FWIW here's the cam i used:
https://www.summitracing.com/parts/sum-4400
now their specs are slightly different than the card that came with the cam but really close! the @0.50 is off by 1 point but the advertised duration on the card says 262 and 272??? but i went with this cam for the fact i wanted to keep the 351W firing order and more on the exhaust side since fords suffer on the exhaust Confused it runs smooth, a little lopey idle, good torque

Ok, so let me get this straight.  Y'all are saying I need to replace the rear gears with 3.50?  Wink
Ok, Ok.  I hear ya.  LOL 
 
Better intake & carb - Check, I've already got them, ready to install.
Dual exhaust - Check, currently it doesn't even have an exhaust.  It actually has some brand new cats, but they're coming off.  I've already got some long tube headers, ready to install.
Smog Pump / EGR - Was planning on ditching that crap.
More Cam - Working on it.
Plus, I've got some cool finned valve covers and chrome air cleaner - We all know that adds at least 5 hp, right?

A local friend of mine who might help me likes lunati voodoo cams. This one looks appealing but the application chart says it's for a 69-85 351w. Will it work in my 302? Maybe just change my firing order?https://summitracing.com/parts/lun-10350701/applications?prefilter=1

If you stick with the 302, 2 1/2" duals is a bit large,
a cam for a 351W will fit, the engine will need to run the 351 firing order.
a 351 cam will act more radical in a 302, so a cam that is a little lumpy in a 351 will be noticeably lumpier in a 302.
Finned valve covers will not only add horsepower, but at least 20 MPH on the top end and double fuel mileage.
3.50 gears will make the car a LOT more fun, but will make the car busier at expressway speeds.
The above post should be read in a "Grumpy Old Man" voice.

^^^ oh that's right! Shocked yes those fins will allow the air to flow over those fins lengthwise, and should increase your top speed, especially if they are the old cal custom style fins!!! and make it more stable on the straight a ways WinkLOL

'rebuilder' pistons usually over compensate for the increased bore diameter with an excessing capacity dish to prevent the rebuilt engine from getting into an octane requirement problem
 
if you're going to re-cam the engine using the existing bottom end, make sure you don't choose a cam that asks for more static compression ratio than you have, overall performance will suffer due to reduced cylinder pressure. in general performance cams assume that you will have better than stock static CR, you'll want to choose a cam that improves cylinder pressure. indicators will be short advertised and .050" duration numbers and low or no overlap at all
 
the 'hotter' the cam the more static CR it wants

Any recommendations on ignition?  Will my existing Duraspark II be sufficient?  I found this post on HAMB, where a couple of folks actually recommended the Duraspark over HEI and others.
