5 Speed swap

If you are happy with a large rpm drop between gears, go for it.
A first gear ratio of 3.83 to 1 is worthless in a car unless you’re just cruising. The 1.5 ratio drop to second gear is close to the 833 overdrive. If your car had any performance cam in it, you either have to short shift from 1 to 2 or have acceleration in 2nd be sluggish when you run it to 5500-6000 in first.
It is your decision. It is best to make them with all the information you can collect to know what downsides you’ll encounter.
The 2.76 gear ran through a .69 final drive is fine for a stock engine but horrible for an engine with a lot of duration in the cam timing.
