rocky; i'd love to tell you that spending a bunch of money on truly rebuilding/machining your 3800 is worth it....but ive gotten burned..twice....
and when i say rebuild, i mean crank turned, new cam bearings, rod bearings, main bearings, block line honed, decked, heads setup, push rods measured, etc.
and it failed before i even got it off the jack stands with a spun rod bearing. took it back for warranty, they did a repeat of the work, now im about 7k miles later... and have low oil pressure. i'm about $1800 deep into just the motor with machine work, gaskets etc..all labor myself.
go buy the $400 junkyard motor and smile.
