@cf6mech would you be willing to let someone ride shotgun next weekend? PM me if you want to . When my engine goes this will be my swap!

2.66 or 2.97?

Not sure which option Vorshlag picked for the Tremec, but I'm sure it was the correct one of the two, they worked directly with a Tremec rep. and are aware of the ultimate purpose for the car.

Right on.
That is a sweet gearbox my friend.
Can't wait for you to get down with your fresh machine.

I'm not expecting it back anytime real soon, there's still work to be done and then debugging and track testing later. No problem when its done getting a ride.

Its probably my favorite part of the swap,...wanted this same gearbox for my Boss Mustang as I wasn't to pleased with the Chinese made remote shifting Getrag

Sorry, another noob question.
What is being asked here?

The t56 has two different first gear ratios available. 2.97 is (obviously) shorter, but slightly weaker than the 2.66 first gear ratio.

Thanks @civicdrivr.

Next "I have no idea about these things" question.
Given the smaller mass of this project car might a 6 speed box result in too much ratio overlap? That is, given the lowish mass of car and monster torque spread of the V8 might a 5 speed box suffice?

Yes, a 5spd would probably work better with a 2.97 ratio while the 6spd would better suffice with the 2.66. Im guessing since A LOT of thought, years, and effort went into this R&D and swap kit; im assuming they realized 2700 lbs and 350whp is good enough reason for the 2.66 first gear

Its always nice to see people asking questions about cars after reading/doing hobby research. Reading only gets you so far before questions arise that need to be answered, keep at it Capt

As far as the transmission applied in this swap.
Two Gearsets are available as follows.
1st--2nd-3rd-4th-5th-6th-Reverse
2.66 1.78 1.30 1.00 .74 .50 2.90
2.97 2.10 1.46 1.00 .80 .63 2.90

Both choices we have a double overdrive.
Meaning for every 1 revolution of the crank into the trans,
you get more than one revolution out of the output shaft, and driveshaft.
ie: in 5th and 6th gear

Also 4th gear being 1:1 means,
In 4th gear the Crank spins once the output shaft spins once.

I'd rock the 2.66.
Enough torque to accelerate in whatever range.
Highway cruising like a champ.
That being said I would do either in a heartbeat.

Its easy to get confused here.
Some say final drive is the Ring and pinion (differential) Ratio.
Other say ▼
Final drive is the Ratio of,
Final gear ratio(♠) times Ring and pinion ratio (♣)
So, ♠x♣ = Final Drive.

Some also include the above along with factoring overall tire circumference.

This post is not to tell you which way is right, its for your info.
My Opinion▼
I've always called Final drive the Ring and Pinion Ratio.
Actually, I rarely use the term Final Drive.

The way Ratios are measured is as follows.
The rear differential for example is 4.1:1.
So it takes the driveshaft rotating 4.1 times into the diff to spin the axles one time.
Hence the ratio of (4.1 to 1) or (4.1:1)

As far as the transmission applied in this swap.

Also 4th gear being 1:1 means,
In 4th gear the Crank spins once the output shaft spins once.

So,
assuming the rear differential remains stock gearing = 4.1:1 ratio.
The 2.66 having a .50 6th gear
The 2.97 having a .63 6th gear

Final drive on 2.66 is 4.1x.50 = 2.05:1
Final drive on 2.97 is 4.1x.63 = 2.58:1

I'd rock the 2.66.

This particular car is using a Magnum box, so the 5/6 ratios are not necessarily tied to the 1/2/3/4 ratios. Assuming this car is running a 2.66 box, there's a very good chance 5/6 is .80/.63.

What are they currently working on, specifically?
