My first car at 15yo was a 1970 Pontiac LeMans with a very tired 350 which was on it's last leg. About a year after buying that car, I found a 400 engine listed in the local paper for $100 IIRC, so I bought it and spent the next month swapping out the 350. The new engine ran great but had the power of a straight 6, zero to sixty in just under a cup of coffee. Took the car in to shop class one day and a friend decided to look up the numbers. Low and behold it turned out to be a 326.
