Is this the correct doner car?

I have a 91 convertible mustang origionally came with a 2.3 previose owner swapped in a 455 buick and I bought it as a roller. Still has 4 lugs and the rear has a "spool" that I suspect is just welded gears.

I have found a 2000 gt that has been wrecked. The hubs and brakes look ok but the lower drivers control arm is bent. So 1st is this the correct car to get a 5lug conversion and brake upgrade from? 2nd how can I tell if the brake hardware I need is damaged too. I have done this research once but memory and the that I am a visual learner makes the articles I have read harder to follow.

Then we get to the engine swap part. The price of this car is what is pushing me to go with a 4.6 as aposed to a 5.0 or some other swaps I had in mind. That said the motor in this doner is most likely bad. I say that because I assume it is an interferance motor and when the car was wrecked it went through a fence and a post went through the hood and busted the valve cover and took the timing gear with it. So not only am I worried about bent valves from a broke chain I worry that the cam on that head may be warped now from the impact. A longblock would fix this but that is were questions come up. Just what would I be able to get a longblock from? As far as that goes with this transmision I could use any modular motor I believe. So what would be some cheap alternatetives or are there?

Any way I just wanted some feedback before I go get this car tomorow

IMO the price of salvage yard 4.6's is sooooo low in general that you should NOT get hung up on this particular 4.6 over the rest of the "fish in the sea". You are correct about the 4.6 being an interference motor. I wouldn't touch any 4.6 with timing set damage for that reason.

Check out for examples of other 4.6's in your area. Don't forget to search on Crown Vic, Town Cars, and Grand Marquis.

IMO you should focus first on what the over all "plan" for the project is. It's not as easy as you might think to put a modular motor in a car that did not originally come with one. The decision should depended on factors such as "your budget", "your plans", and "YOUR SKILL SET".

Read the following thread:

You may find doing an old school OHV 5.0 is easier.

I'm not an expert on exactly which model years are best to use for the 4-5 lug conversion. However, I don't think that the 1999+ are it. Something about the width of the rear end. But maybe someone with more specific knowledge will chime in.

If your talking about the transmission in the 2000 GT it is a T45 not a T5.

I also wouldn't take that motor as a reasonable doner because you could get them just about anywhere without the chance of that motor being bad because of the damage it has undertaken.

It wouldn't be the easiest swap plus the 4.6L 2v isn't the top choice to spend that much money and time on for a swap.
