RV Repair: 318 Engine, class c motorhomes, class a motorhomes

Question
Can you tell me what years the 318 engine was used and what manufacturers.
Thank You

Answer
Ray,
   The 318 motor is, as far as I know, only built by Chrysler.  The first block (A) was used from 1957 until 1967.  In 1968 they changed the block (LA) and that motor was built until 2002 when it was replaced by the 4.7 liter.  As far as what manufacturers I assume you mean RV's.  Any and all could have possibly built their class C motorhomes on Dodge van chassis's and a lot of them did.  There are quite a few smaller class A motorhomes with them as well but the 360 was  more common for those with small block motors.  I hope this helps, good luck and happy camping.
