Build Specs 1.0:
I carefully chose my options. I might have revised no less than a dozen times. Here is what I ordered. If it looks like basically everything it almost is. The points I am still unsure of is the wilwood brakes (nice for the track) and the IRS vs the 3 link but IRS seems nice and modern.
Complete Coupe Kit
Powder Coating Gen 3 Coupe Chassis
Body Cut Outs
Low back Vintage Race Seats (will change for high backs at some point in build)
IRS
Center Section and Spindles
Gen 3 Carpet Kit
Side Window Components
Coupe Nose Scoops
Front and Rear Sway Bar
Wilwood Front and Rear Brakes
Koni Dual Adjustable Shocks
GPS Gauges
Halibrand 18" wheels
Windshield wipers (might not install, will have to wait and see)
Battery Cut off Switch
Coyote Install Kit
Coyote Headers
Coyote Power Steering
Now the wait and let the reading of the build manual a million times begin. :confused:
UPDATE: BUILD CHANGED AGAIN FROM COYOTE TO 427 SBF SEE POST BELOW:

Some Thoughts:
The voodoo engine is likely off the table, though I haven’t completely nixed the idea. The flat plane crank is what I’m after. After all we are building a race car why not give it a race style engine. That said it’s very complicated. The software programming on the ECU is going to be in the thousands, money I’d prefer to spend elsewhere.
My plan is to get a Gen 3. I am in fact going to do a T56 magnum. These new gen 3 coyotes can rev quite high so I really want to go with something that can support it.
I tried finding a 3.73 rear end but have failed to find one on the shelf. That's what the Boss 302 had in it. That said I drove the 2018 Mustang GT which has a variant of the Magnum according to Tremec and that is a equipped with a 3.55 and it was snappy. I would still prefer the 3.73 though. Any leads would be excellent!
The wiper blade kit I’ll struggle with it will keep me entertained or frustrated or something. LOL. Again not sure I even intend to use them. In Los Angeles rain is a novelty these days.
I started my build thread because hopefully this preliminary discussion helps someone and ME! LOL. Spoke to Ford the new Gen 3 Coyote part number is M-6007-M50C. MSRP $9500
Any help with that rear diff would be appreciated. Thanks!
Build Specs 2.0 - Change of Engine
So after all the coyote discussion. I've scrapped the plan and I am going to do a Small Block Ford (SBF) engine with EFI. FFR was nice enough to make the change. Had a very productive conversation with Blueprint Engines. Made the decision for 2 reasons.
1. Factor #1 came about when I was talking with my brother about cars (we love to talk cars together) he made some comment about a replica with a dated engine and it got me thinking about other peoples perceptions of the coyote platform over time and how they might see this car in 10 years. In my short term thinking the Gen 2 coyote is discontinued. A more advanced engine has come along. The Gen 3 and by all accounts it a major improvement but frankly looking at Edwardb's build the gen 3 is off the table. It is just too much to bite off. I am not capable of taking the time learn how to alter the engine like he is and run my business and wrangle our 2 year old. Thus leaving me with the option of a gen 2 "a dated engine" (as my brother referred to it.) Additionally I felt pressure to buy the Gen 2 engine and transmission now because of supply concerns and didn't want to drop $15k on an engine and transmission and have it sit in my garage for a year while I put the car together, the warranty clock ticking and the money locked up.
2. Factor 2 came about when a gentleman on this forum asked about the value of these cars and I posted my research. In that research I found a Daytona that sold for $30k with an old Mustang 4.6L engine and really there wasn't much of a difference between the cars that sold for $55k and $72k except for the engine. Though I am building the car for me I always think about the value of what I am doing. What will the car be worth once it's done. That's not the objective though to sell it. The objective would be my son takes his prom date to the dance in this car (safely). So, what would be the value of the car in 15 years with a Coyote engine? I don't have a crystal ball but my psychic tells me it's not going to be as valuable as a 427 regardless of the age of the block (just kidding on the psychic, it's intuition).
I want to throw out a disclaimer. My no means do I disagree with anyone's choice of engine this is your car and I just love the fact we are all here talking about it. I am just sharing my thought process in the hopes it helps guide someone because frankly I almost cancelled my build because I got so frustrated by my confusion. Note, none of my decisions where based on what was period correct (though argument 2 might have some relevance to that).
Updated: For continuity I am including the link to the thread regarding ordering the beating heart of this build. The Roush 427SR. I have learned a lot researching the SBF since my first posts and I am working out details on fitment as of right now. Likely will order (put a deposit down) before Christmas to lock in the price on the engine. Roush will hold the engine till I'm ready for it. Warranty starts 90 days after I receive it. I don't anticipate needing it for 6 months.

Build Day 1 - Bolting Wildwood Rotors Together
Wow a super awesome package arrived on Friday!!
Attachment 100330
Guess what!?!? This marks the official start of the build! I wasted no time getting to work. Started by nesting AKA rearranging my garage. Worked all day Saturday on that and then started in on the Wildwood Disc Brakes on Sunday
Attachment 100331
I torqued the bolts to spec 155in/lbs and used required locktite and marked each one with a paint pen and a line extending from the top of the bolt to the rotor so if they move it's easy to see on inspection
Attachment 100332. Attachment 100333
I was under the impression that the calipers needed to be assembled but at first glance it looks completely assembled. Check that off the list. Here is one initial hiccup. Wilwood very nicely explains that the .032 safety wire that is required is "cheap" but they also fail to include any of the required "cheap" safety wire... :confused: So that has to be ordered.... So make sure you buy that before you start your build I bought this Malin - MS20995C Stainless Steel Safety Wire / Lockwire | .032" Dia. There were some other thoughts but I can't remember what they were at the moment so I'll update when they come to mind.
If anyone needs the wildwood instructions for whatever reason I can upload pictures of them. Safety Wire Instructions can be found here: http://www.wilwood.com/pdf/datasheets/ds386.pdf
Once the wire comes and my safety wire pliers I bought arrive I'll get started on that. Kit completion date is this Saturday then the wait for Stewart. Though I am not in a rush to spend another $2,000 for shipping to California so I can be patient. LOL.
Just for reference assembling all 4 took me 1 hour and 15 minutes. I threaded each bolt on half way to confirm alignment of the rotor to the hat before torquing anything down so this technique took a bit longer.

Safety Wire Wildwood Rotors - Day 2
Just as a piece of information installing the safety wire on the first rotor took me 40 minutes to complete. Mind you it was my first one and I am not trying to pump these out but it goes quickly once you get it dialed in. I want to share some tips or instructions since there really isn't a guide to how to do it, just a picture of the completed product. Also if you are exploring buying a kit it's nice to see peoples approach and fill in the gaps of the instruction manual so you know what you're getting yourself into. I like to build everything in my head before putting my hands on it.
Step 1: I took my .032" safety wire and measured out 14". After threading it through the bolt perpendicular to the rotor, I grabbed it and bent it up at an angle with a set of needle nose pliers.
Attachment 100391
Step 2: It's really hard to pull the wire through with a needle nose. It's simply not going to do the job so I attached my safety wire pliers (these are the one's I bought on Amazon they are great) and pulled it though
Attachment 100392
Step 3: This part is tricky. Where to place your pliers so don't over twist or under twist the wire. What I mean by that, is not to twist the wire so far that you have to untwist it to get it into the next bolt or too short and you find that the twist doesn't make it all the way to the second bolt hole. I hope that makes sense. If you line up your pliers like so (see picture below) you will have the perfect amount of twisted wire between bolts. I attached my pliers to the wire just a few millimeters past the bolt hole. This took me a couple attempts to get it perfect but I took a picture to mark my distance past the hole once I got it right and it came out great.
Attachment 100395
Step 4: Thread the wire through the second bolt hole and the other wire around that back side as shown in the picture below. Then take both wires and thread them under the twisted wire. If you don't the wire that wraps around the back of the bolt will want to jump up above the bolt and you will find yourself struggling to get it to sit back down.
Attachment 100398
Step 5: With the wire perpendicular to the twisted wire as seen in the picture above. Go ahead and twist it in this position. As the wire begins to twist and tighten soften the 90 degree angle (perpendicular angle) to a 45 degree angle and cut the excess with a snip. I cut about 3-4" of excess wire off.
Attachment 100399
I thought about doing this without the safety wire pliers. My advice is don't. The pliers make the results so easy and so professional it's well work the money. Here are the tools I used to complete the job
