Hello all, my first post here.
I too am going with a 460 in my 67 Mustang coupe. Been stockpiling parts for the whole job for a few years now. I'll lay out my plans, which may help with some of the questions this job would entail.
Will it fit? Yes. The 460 is 1" narrower than the shock towers. lol It's heavy though so aluminum heads are a plus. Maybe even a fibreglass hood, battery in trunk, etc.
I've read it's easier with manifolds or shorty headers though. Full length headers might mean lots of tweaking for fit.
Check out Edelbrock dot com website, and check out the dyno tested cam/intake/carb/head packages for 460's.

I considered the stroker kit too, but decided to stick with stock cubes for now.
Increased weight and power mean bigger demands on suspension and brakes.
No choice here, upgrade both. I chose Ford front spindles from a 71-73 Mustang. They bolt on to 67-68 Mustangs, give you a larger spindle diameter, larger wheel bearing, larger diameter front rotor (1" bigger than stock 67 disc) and they are pretty cheap and easy to find in scrapyards. Just make sure to get the proportioning valve off the donor car as well. Also use 71-73 outer tie rod ends. :)
The rear is optional. I have a Lincoln 9" rear end I was considering narrowing
but will probably go with an "off the shelf" bolt in rear end with discs.
A rust free 1967 coupe. Subframe connectors. 8 point roll bar (S+W race cars). Custom "steel boxed" upper and lower control arms with larger balljoints (Maier). Polyurethane bushing kit for whole suspension. Large nonstock front and rear sway bars (Maier). Underhood montecarlo bar.
(all above purchased so far)
Steering. Probably go with a total control products bolt in rack and pinion.
Newly designed specifically for this model/year of car. Their website even has a link to a detailed description of the install. (it's $3000 with power steering, so i'm still saving up for it) lol Also noticed the steeroids ad, on the forum. Might go with one of their power units and mate it to the stock pump? Might be a bit cheaper.
Custom radiator. No way the stock one will cut it. lol
Aftermarket waterpump, or 1969 Tbird 429 short shaft stock pump
After market motormounts kit, or 1969 Tbird 429 mounts (supposed to bolt in)
I've probably forgot something but that's most of it so far. Comments?
PS, I'm not actively assembling yet. And this is supposed to end up primarily a street car, with occasional drag racing here and there.
