·I'm trying to find out the year of my engine. Does anyone know of a site that lists engine info by serial number? I have a 59 CJ5.

this may or may not help you
on an AMC V8 the date is cast into the distributer housing on the duraspark ign models.
the build date is stamped onto the inside of te timing cover
there is a build date code on the exhaust manifolds too
Ive seen date stamps along with over sizes printed onto crank bearing shells
now I realize its likely for all of these bolt on things to have been changed, but its a start

77 CJ5, in a bunch of sanded and primered pieces

here you go..
the engine number is located on a pad behind the water pump on those 134 ci fours and on a pad on the block deck visible between the first two exhaust manifold runners on the passenger side for the v-6. if its a four cyl. up to 1967 will start with a 4J followed by a six digit sequential serial number.
1st digit=market=M-military, E-export, D-domestic
2nd digit=year=L-1965 v-6, M-1966 v-6, N-1967 v-6, P-1968 v-6, R-1969 134&v-6,S-1970 134&v-6, T-1971 134&v-6
4th thru 6th digits=build date
7th & 8th digits=internal dimensions=A-.010 undersize crank and rod bearings, B-.010 oversize bores, M-.010 undersize mains 134 only, P-.010 undersize rod bearings 134 only, AB-.010 undersize main and rod bearings
9th digit=type=S-service engine, R-short block
10th thru 11th digits=134 compression ratio=60-6.0:1, 63-6.3:1, 67-6.7:1, 71-7.1:1
hope this helps some..
