With proper oil and cooling, How long would an engine last at say, at, or just under redline? Also, how long would would an engine last at top speed? Would it run out of gas first? what about the transmission? Would a ferrari or lambo last longer than a normal car with a lower top speed?

There is no one hard number. It really depends on which manufacturer made the engine and how well it's been looked after.
I remember years ago, someone I know told me about a motorcycle rally he used to attend in his youth and one of the annual traditions was to take an old motorcycle and lock the throttle fully open. They took bets how long it would take for the engine to either seize, throw a rod, etc. Some of them would go for quite a while others self-destructed under a minute.
DEPENDS on how the engine was DESIGNED! EUREOPAN engines and NOW many DOMESTIC Ones use OIL SPRAY JETS that focus clean oil At the piston WRIST PINS< and SKIRTS! This LOWERS FRICTION and allows for SAFE HIGH SPEED ENGINE RUNNING! OLDER cars like in the original CORVETTE cannot run very long on the AUTOBAHN as they just BLOW UP! OIL SPRAY JETS have been used by VW BUGS for DECADES now! ALL EURO engines feature this type of thing, And now MOST American ones have it as WELL! TOUGH QUESTION< TOUGH answer! MOST engien wil NOT do well at those speeds< BUT>>> Now many engines used by GM< for example use OPEL TURBP engines from GERMANY and some use SAAB derived engines from SWEDEN! They WILL last at highest speeds, cuz they have OIL SPRAY JETS inside them! CLEAN OIL Lis focused RIGHT at the piston WRIST PINS and SKIRTS and under the engine block where the piston travels! Thays can last FOREVER at high speeds! In EUROPE there are MANY ROADS with NO speed limits! We are SO backward in the USA! We have NO bullet trains or MAG LEV trains! We are mostly CONSUMERS. I EVEN texted silly TRUMP ONCE with the idea to redo the DETROIT TRAIN STATION< that has been IDLE for decades, and install MAG LEV TRAINS going to CHICAGO< NEW YORK< D.C. and BOSTON! He never answered! He is TOO BUSY covering up his MISTAKES and sending out ANNOYING TEXTS about how GREAT he is!
Until it blows up :)) Seriously likes already been said engine manufactures a big part of it however But a give you a bit more of an answer yes will run at top speed until the fuel Runs Runs out but Won’t do the engine any good and especially on red line. Where it out faster
A race car probably runs on full throttle about 30% of the time? Rebuilds are usually done after a few hundred miles. So for a production engine, I would guess about 100 miles at most . A Ferrari or Lamborghini would probably last longer although full throttle would be at higher revs. Doubtful if a tank of fuel would last that long. Supercars do 1-2 mpg when flat out.
what car have you driven that could make redline in top gear? How long did you hold it at full speed? Where the road is long and straight enough to hold it at full noise for a couple of hours you cant carry enough fuel to make the next stop.
