there will be obviously a large variance.
i can tell you this though. my friend had a 25anniv (92 i think?) camaro with a 305 and he ran like 17.x@76 (i forgot, it has been a while) that is so slow!
another kid has a 91 firebird with 190k on it (the rs only had like 70k!) and my friend can take him by a nose in his 96 jeep cherokee with a 5.2L, fulltime 4wd, 4500odd pounds. it runs 17s.
