replacement engine resources??

Hi All,
it looks like im eventually gonna need to replace the 2.0 in my 1988 Ram50.
Im looking for suggestions for a reliable engine refurb/sales business in The States.As close to California is good (shipping is going to be expensive!).
Thanks for any thoughts!

I think when my dad replaced the engine in my truck he got it from Jasper Engines:
