Replace AMC 360 with 304
 

I'm replacing my old 360 with a remanufactured 304 in my CJ7. Is it possible
to tell from which year an AMC engine is build ?

Any other things that I should consider, for example 360 parts that doesn't
fit on a 304 ?

Regards,
Thomas

Will the numbers on the side of the block tell you something? Or maybe if
the size of the bolt holes are different for either the exhaust manifolds or
the alternator might give you a clue to the range of years that motor was
built.

AFAIK supposedly the Harmonic Balancer and the DrivePlate/Flywheel are
balanced differently.
Make sure that little bushing inside of the crankshaft for the Torque
Converter is correct for your year vehicle and trans.

I had installed a 304 in my 79 Wagoneer. I even used the 360 HB and
Driveplate along with the intake and carb. I had no problems and drove it
for about 8 years while getting about 15mpg highway.

Good luck and have fun! ;-)

If you go here: <URL:http://www.amcrc.com/tech/tech.html>
and page down to the section "The AMC/Jeep V8 (290cid, 304cid, 343cid,
360cid, 390cid, 401cid)" you'll find these two links:

"V8 Cylinder Head identification information by Casting Numbers"
<URL:http://amccf.com/tech/heads.xls> An Excel-format chart that lists
head casting numbers from 1970 to 1981.

A few lines down you'll find "V8 Engine Specifications (Dimensions,
Camshafts, Connecting Rods, Pistons... (from '75 TSM)"
<URL:http://amccf.com/tech/v8_specs.html>. It might be useful to you.
Note that a lot of the sections are common for the 304, 360 and 401.

This link: <URL:http://www.butlers-a1.com/amcm.htm> isn't very detailed
for your application but it might help someone. It gives block, head
and crank casting numbers for a variety of AMC engines.

You of course know that the easiest way to ID and date an AMC engine is
to decode the Engine Day Build Code:
engine<URL:http://www.amcrc.com/tech/engine.html> Of course since your
engine has been remanned it might not have the original tags on it.

This guy says that "the AMC 290, 304, 343, 360, 390, and 401 all share
the same external specifications, and the intake manifolds interchange."
See: <URL:http://www.carcraft.com/techfaq/116_9906_guide/index3.html>
(A junkyard engine spotter's guide.)

This site agrees:

All AMC V8s were made from the same mold, the differences are all in the
bode and stroke. Absent a valid EDBC it looks like the best you can
hope to do is establish a range of years that your block was made.
