Welcome from West Virginia! Interesting idea.

 
Welcome from North Carolina. I would go with the 5.4 or 4.6 you can get way more HP than the 460 will give with great gas mileage and very dependable. They are a tall fat engine for sure I dropped a 4.6 out of a highway patrol car in a 1950 Ford business coupe but have never got finished. Fatman 2" drop spindles and dropped Maverick rear.

We like pictures so post during build.

Ambitious project. Look forward to seeing what you can accomplish. A blown 521 would put out a lot more power than the chassis or rear end set up you are proposing could ever handle effectively. You'll need to really think through your plans carefully to make it work right.

You might want to look at a complete framed chassis such as Art Morrison sells or something along those lines if you are going to build the car to that level.

 
The problem I think I'd run into with a 4.6-5.4 is the deck highly I'd like to keep a factory hood on it


Also the width of the heads coming into contact with the shock towers

I dont know anything about a 4.6 or 5.4, but can they really make more hp than a 460 based engine? 460s can be stroked to massive cubic inches and support huge hp.

Like i said i know nothing about the 4 6 or 5.4. Just curious.

When Ford stepped back into the road racing world everyone said the 4.6 was too heavy and that the car did not have enough brakes. They went out and beat the BMW's, Mercedes and all the American vehicles in the first race. They kept throwing weight on the mustang to slow it down I think they threw 200 more pounds of weight on them so the others would be able to compete. Things like forged powdered metal rods and 4 valves per cylinder, variable cam timing just are worlds ahead of just cubic inches. The OHC is also a big advantage.

I think when I measured engines the 4.6 I put in the 1950 ford was a little more narrow than a Boss 429. It fit in the 1950 Ford and still had the stock inner fenders. Biggest issue was getting the engine back far enough. You should have the second spark plug about where the centerline of the front wheel is to get the weight right. That ment firewall had to move.

I would think a 71 - 73 would have plenty of room.
