There is no HP gain. There are advantages....if you work on the car yourself. You can pull off the TB without having to worry about coolant. The same is true if you have to pull the plenum and things below.
You will get a little cooler air into the TB and plenum, but it will not be measurable.

You do not actually block off the hose. There is a inlet on the TB on the drivers side and an exit on the passenger side. Take both hoses off and use a pipe to couple them together. At least on my 85 this hose leads to the heater. It is likely the same on other years as well. You can leave the fittings on the TB uncapped, it will be okay.

as above from John, get a double ended 5/8" brass fitting and 2 hose clamps and join the 2 TB heater hoses together. i did mine then drove it and didnt notice any SOP difference, however the next time i drove the car it was hot, over 100F, driving down a 80 kph (about 50 mph) road with lots of traffic lights so driving it easy (no air con either !) i noticed the mileage went from a best of 12.2 litres per 100k to 11.2, which converts to 21 mpg, i have had the car over a year and it had never got better than 12.2.

I agree, it will only take about 4' of hose to route it around the outside of the engine. A few large black tie wraps help hold the new hose along it's route,
