@msjulie You know I reread this post and it just dawned on me that you ordered a car from Vintage, and an engine from Outback, now called Outfront, so congrats.
A Stock Subie with minimum mods will be a pleasant car to drive, enjoy the build process.
One precaution, check the oil often as these engines can sometimes use a bit of oil and even subaru new cars have that warning. Just don't get caught with the low oil.
