Because of it's bigger bore, the 427 has more potential for cubic inches and a better selection of heads than the 428. It can use any FE head. The problem is price and availability. 428's on the other hand can still be found fairly easily, and will make just about as much power as you want depending on how you intend to use it.
As usual, it all comes down to money. If you are a fan of the FE stick with it. If not, then the 460 might be the route for you to go. Although I have a very high-end FE, and am very happy with it, it is my personal opinion that the 460 can make more power for the same or less money, and has a bigger cubic inch potential. I'll probably get flamed for saying so, but it is hard to argue otherwise.

I don't think anyone will flame you. At least I would hope not.
I think you've got a lot of creditability here, and like you said, "the 460 can make more power for the same or less money, and has a bigger cubic inch potential <> it is hard to argue otherwise."
I think that's right on, but FE's are cool none the less.

Well I have done some research on this...as I think alot of the guys have...The FE is a great motor, but like Scouder said, the bottom line is its intended end use?
For my 433 Cobra build when its done, I'll have about $6000 in it for about 550+HP, Now with that said, I'am also putting together a 460/521 Stroker with about $2000 in the botom end and machine work, $1400 in port and polish on Iron heads and the Victor intake reworked, heads with 2.250 int. vavle's and 1.800 exh.-Solid roller cam with about .650/.650 lift , roller rocker and lifters another $700, and $700 for a carb..
Were @ about $4800 and some change, for 600+HP and about 625Lbs of torque?
And thats easy streetable HP.. the engine is capable of 700+HP with just a cam change, but would not be streetable!!
What ever you choose! Good Luck.its Fun!! Russ

i have a 460 in a 79 4wd that is mostly stock and i have another that i am rebuilding with flat top pistons 40 over, high lift cam, early higher comp heads,headers and dual exhaust and 750cfm carb ,edelbrock intake,with machine work and work to the heads i have estimated(doing alot myself) total build to be under $2500. it will probly be pushing real hard on 500hp-plenty. but with all that said it doesn't have the mystique of say a 429BOSS or 428SUPERCOBRAJET or even better a 427SOHC and if i ever finally get that 68 fastback its getting either a 428 or better yet a 427 -now that has anice ring to it .427 mustang i like it. well thats the plan anyway.

If someone flames you Scouder 
to them!!!!
It is up to Rory to let us know how the engine will be used. The 427 will rev a bit higher safely, but the 428 will make more lo rpm torque. Both will make gobs of power for a Falcon!!
Availability and torque goes to the 428, but HP goes to the 427. What do you want??

Scouder,
you obviously have no idea what you're talking about. The FE motors kick ****...460s suck....

427 like more rpm's, due to short stroke. 428 are better torque builders since they have a long stroke.
Anymore, either one will cost you dearly to build. They are casting new 427 blocks,not 428's. But, that is if you have $3-4K for a block only. NOS parts are even higher. With the heavier weight of a falcon, I would probably pick the 428 for the torque(falcon is like a torino over here, right?)
Best of luck with project.
PS: ya, the 460 is cheap horsepower.........but NOT in my garage it isn't

What year XB Falcon? If its what im thinking about id go with either one, just lighten it up with some aluminum. And if it was mine personally I'd go with a 351C , but thats a no no here{substituting an FE for somthing smaller might get me ran over
} and its also not my car. if it was a 73 id love to have one though.

The Aussie Falcon are a bit different than the small compact Falcons over here in the good 'ol USofA. IMO, the US ones are a better body. Especially when yer talkin 63 sprints and the 64-65s......
My first car was a 65 falcon w/ the 200-6cyl. I am currently just getting started on a 64 sprint project. The motor(260) and drivetrain is done. Now it's time to start on the interior/exterior.

I wouldn't look at either the 427 or the 428. I'd build either a 390 or 410. MUCH more available, and affordable. Any time you build a factory high performance motor with a history like that, you're going to part with big $$$$. A built 390 or 410 will provide much better results for the money.

thanks for the backup Rusty. But, I have to confess, since it may not have been opbvious; I was being a little fecitious! Scouder was worried about getting flamed, so I flamed him. Or I tried. I'm not very good at it :-)
Anyway, it was all in an atempt to be funny.
Now, I do love my FEs. I think it's worth considering the FE, especially if your vehicle is already setup for an FE. You might be able to save enough $$ by building a 460. But, there is still some time put into the conversion. And, theers more FE parts available now. youve also got a wealth of knowledge right here at FTE.
Rusty makes a good point about the 360/390 block FEs. If you start looking at 428 or aftermarket cranks, you can get plenty of displacement.
