Thats what I was afraid of. I find youtube very frustrating with all the rambling and ads and clickbate video titles, but I guess it's the way of the future. Maybe I am old school, but I think a webpage of good facts is mountains better, but yet hard to find. I also noticed another anomaly that a manual pull on a car with a high 0-60 can slay a car with lower 0-60 stats because they are for an automatic transmission, especially if you start in a higher gear (my old 1995 Pontiac Trans Am car actually had a button on the automatic transmision called "performance mode" that would start the car in 2nd gear for launching it). I've earned about 10 million dollars in the game grinding but it burns up fast buying cars just to see the engines and then selling them for less but maybe that's my best bet, if I don't want to sit through youtube videos. I wonder if anyone would find a list useful of what I find if I compiled one and posted it. The closest thing I have found is https://nfs.fandom.com/wiki/Need_for_Speed:_Unbound/Performance/Engine_Swaps ,
but the problem is that it requires a person to click on each engine and then scroll to find the cars, which is very slow and tedious unlike a spreadsheet. I have also found some others but they are all for "NFS Heat"
