That was 68 coupe,

Cam-ology (dat a word?!) has come a LONG way since the "alphabet cams" were the go-to in SBF's.
IF that's what you have........then that's a different story.
1......with 393 cu. in. engine the LAST thing you need to be concerned with is low-end grunt.
2. why deliberately "strangle" the engine with a too short/to small cam?
3. stump-pulling low-end torque can be achieved with gears if that's the main issue.
4.great heads and healthy stroke screams for a camshaft to feed them at your desired RPM.
5. I'm a huge advocate of having a custom cam ground for a special engine.
      (with your 'brains' and experience and mechanical inventiveness DON'T ask some sales clerk to send you a..
        "Chevy-grind-made-for-a-Ford" bump stick!!)
6. I like......(anybody wanna guess ) a cam with NOT too much lift(save those springs & valvetrain)
    medium numbers on duration 230-240 duration @050 and LSA around 108*. Like Ed Iskendarian promotes. Power band from 1000-5500RPM.
7. Custom ground cams are the same price (or LESS)  than 'shelf grinds' (developed on GM engines!)

IF you already HAVE the 2 cams.....I would use the 303 E

Sall, I am completely shocked that your answer is "more cam" 😂😂😂  I have the F4TE cam but not the E303.  I plugged in the numbers for the E303, Lunati  20350612 and a Voodoo cam.  The curve was very similar for the E303, Lunati, and Voodoo cams + or - 5 with the same basic RPM range.  I put up info for the E303 because it was available where the other two were backordered.  I am actually hoping for higher gear ratios to make this more of a cruiser.  My cam choices are limited by a max lift allowed by the heads of .550" According to my desktop dyno with stock heads and the F4TE cam the torque curve began falling hard about 3000 RPMS.  The improved flow of the heads i'm using got me an extra 1000 RPMs.  This may be a dumb question but where do you go for a custom cam grind?

Call Crane's tech department.  Give them all the information they ask you for.  Buy the cam they recommend.  Bottom line: the truck cam was designed for a truck.  It was also designed 20+ years ago and had a host of requirements it had to meet by which you are not bound.  The E cam was designed for a 5.0 Mustang.  It was also designed 20+ years ago and had to meet a host of requirements by which you are not bound.  IMO trying to pick a cam with what any of us know is about like any of us trying to perform surgery.  We know about enough to be dangerous.  Crane was the first to the aftermarket with Ford rollers.  They've logged millions of hours and miles on the dyno and track respectively.  I've had them select the cams for the last three engines I've built.  I've yet to be disappointed.

I think......most all cam grinders will make a custom grind if you ask them (for the same money!)

     I'm a big fan of Delta Cams in Tacoma Wash.
Ken ...the phone guy... went waayyy above and beyond to help me.   ex. (when I needed to buy a set of new roller lifters he beat even Summit's price) Super advice and price!
 
Howard also does custom work. They were my second choice.
Lunati Cams also

When doing my research I looked at other cam company recommendations (there charts for SBF)
I also looked hard at dirt track cam grinds  because of (how they sound...naturally ) but also their need for quick acceleration in a short time period.
I wasn't interested in a curve that went from  xxxxRPM to 7500RPM
  I wanted something from just above idle RPM to 5500RPM...like a dirt car.
A tight LSA number 106*(dirt tracker) gives the instant RPM for coming off corners
           and max power down the straightaway.
Since I wasn't interested MAX full-on HP I lowered the lift  for valve train longivity,,,
and went with 108* LSA  to get a little better manners in traffic.
I THINK.........I "hit it outta the park" with...MY choice.YRMV

Here is my two-cents … what are your plans for the car?  How many times do you expect to be running over 3000, or 4000RPM; or even higher?  Is this a street cruiser, street terror, highway runner, racer, etc.? 
It all depends on how you plan to use the car.  Just guessing, but it seems to me, with the weight of the Galaxie, more lower end power (below 3000RPM) is where you’d be looking.

That was exactly my thinking in picking the truck cam.  The car is a cruiser no drag racing or track racing AND it's a MT car one of only a few states where you can drive for over 767 miles and still be in the same state (Yaak to Belle Creek) and on both ends you still have a distance to go before you cross over into the next state.  In other words a car for LONG drives.  The current rear end is a 3.25:1 with a 2.95 1st T5 but 1st on the TKX is 3.35:1 so I will likely be putting the 3.0:1 that came in the car back in it.  I like 5th to be less than 2000 RPMs.  I realized the image I posted earlier was for a different cam.  This is the actual comparison between the F4TE truck cam and the E303  green and red truck blue and yellow E303

at 2000 RPM there is about 100 foot pound difference in torque between the two cams but with the E303 cam there is about 75 more max horse power.  interestingly enough I get to similar max torque numbers at different RPMS 3500 for the truck cam and 4000 for the E303.  I am kind of leaning toward the E303 BUT 100 foot pounds is a lot to leave behind at the lower RPMS.  I filled out comp cams cam picking questionnaire but have not yet heard back.  Once I get there recommendation I will put the specs in my dyno and see how it compares to the two Ford cams.

I am going to say none Daze.

If you just had a stock 351w or mild 357w…sure.

I think you might be missing out on additional torque tor the ol’ Gal.
An aftermarket camshaft doesn’t have to be radical to make torque in lower RPM’s.

Daze - you indicated "I like 5th to be less than 2000 RPMs"; at what MPH? 

I don't know, somewhere between 80 and 100

Call someone that has built and dyno'd a lot of the 393 strokers to help select a cam. They will have the real world experience with making a cam choice. I think using either of the cams you have here would leave fall short considering the engine is about 12% bigger than it was. If the new heads and intake flow better than what Ford had, then the short fall in HP and Torque increases. 

What tire size are you running?
What is the ratio for your 5th gear?
