Tilton did not send me the sheets but I looked up some calculations on the internet and made he decision to order 3/4" d. MC. It should increase my power about 35%. Hope that's not too much!
The calipers on it are Sierra brand. Looks like the company is out of business and or bought by Joe's racing parts. I worried a bit about what to do when I need pads but probably I'll never need any due to limited usage.

I've been thinking about the big picture on my Cobra. I have owned two pure race cars, a 1985 Formula Ford and a 2002 built Lotus 7 replica with 16 years of continuous autocrossing with multiple drivers, often three drivers at an event. This cobra has 3000 miles on it so mechanically it is like new.
I am having to sort things but its like working on a new car. So far nothing is worn out. I am changing things to suite my purpose mostly and or sort the engine drivability. I hope to have it ready to autocross on the 7th.

Today I got the calculation sheets from Tilton. I pulled the wheels on the right side to inventory what I have for brakes inside the wheels.
1. Sierra calipers with four 1.75" pucks per calipers....same front and rear. 2. 12" ventilated rotor in front, 11.5" in back, the rotors are bolted to the hat and all bolts are safety wired. 3. It has 1" lug nuts as required for some forms of racing. I am hoping to get the car back together this week so I can sort more details next week and autocross on the 7th.

Today the Tilton engineer asked me to remeasure my brake ratio. I had told him 7 to one yesterday based on the movement of the pedal vs the movement of the input rod on the mc.
So he asked to remeasure the distance between the pivot and the output to the mc and from the pivot to the center of the brake pad. so now its 1 to 6. He likes that better.

Yesterday I peered into the bottom hole of the bell housing at the clutch. The PP housing is orange. Looks to be a Centerforce. All the PP from them are orange. I went to their website and tried to figure out what it is.
I suspect its a two disc with a lovely aluminum flywheel.

The cam is in the engine today.
The Tilton Engineer got back with me yesterday and said to put a 3/4" master in place of the 7/8 for the front brakes and put the balance bar in the center between the front and back brakes. Unfortunately the front master is behind the rear mc and so the rear will have to be removed to change the front mc. So that's what we are going to do.

I had first resisted using the 7/8" mc for the rear brakes because when I apply the brakes now I cannot lock the front or rear brakes.
After thinking it over and discussing it with John, one of my lunch buddies I will do exactly what the engineer said. Putting the balance bar in the center will create higher mechanical pressure on the rear mc. changing the size of the front mc will increase the line pressure for the front brakes. Should do the trick. Woo hooooo!

some sort of custom puffed up version of someone's dream cobra.

Cobra redesigned by a person on LSD.

The title of this thread reminded me of my Saturday, top down drive.
Saturday we took a top down drive through the winding NE Texas hills on secondary winding roads. We drove by a junior college where there is a Carroll Shelby Tech Center that was built with a donation from Carroll Shelby. I told my wife about reading an interview with Carroll not too many years ago in which he was asked the question: what do you do for fun? Or something to that effect. He said that he still has an original 427 Cobra, and getting out on the NorthEast Texas backroads on a nice day was as good as it gets. The thought of it made for a fun drive.

BTW Tom, is that engine a sure enough cross bolted FE? I have not read the entire thread.

I think that it is an aluminum SBC block.

Nope, it was one of Hillary’s friends that she sold the uranium to.
