you can't, they are identicle on the outside. the easiest way is to pull the alternator and find the stamping and look up the suffix.

virtually impossible, good luck with that lol especialy in the late 70s and all through the 80s,
if you know engine is original then you can pretty much figure out which it is by the year make model and application
any 80s cars would eb 267 or 305
any 5 or 10 series trucks 80s would be 305
and it goes from therer
youre best to get a flashlight and a long flatblade screwdriver or similar instrument and a junk cloth and soem carb cleanr or something along thos elines and clean off that deck stamping pad below behind alternator down there where fuel line form pump to carb is supposed to run(factory)
get last three CAPITALIZED letters from that deck pad and look for it here: http://www.nastyz28.com/spmenu.html these are listed in
alphabetical order
or go to google search home page and type in the three letters and then the term: stamping, or 305, or 350, or engine
youll find it and have your answer with not much work or time at all, this is how to check any v8 engines and some L-6(later years called I-6) engines
good luck and happy stamping suffix code decoding

on the back of the block where the bell houseing bolts ( just below the head and oil pressure hole) on the driverside top is the casting number alot of 85 and newer engines say either 5.0 or 5.7 there. its hard to see but fastest way i know, if its not labeled 5.0 or 5.7 get the number and look it up on mortec.com
