Between a 5.0L, a GT, and a Cobra if you heard them all, and did not see them? If all were 100% stock, could you distinguish which is which, between a 1995 Cobra, a 1999 GT, and a 1999 Cobra? 


I can do the same with huey and blackhawk helicopters.

I can tell the difference between a P-3 and a C-130. Same engines just different props.
