        boring and stroking, YES. As for actually attempting to put parts from a 3800 onto a 3.1/3100/3400 block, some have tried it and so far nothing can be used.

        I take that back. The fuel injectors fit.

          you can bore and stroke a 3500 to be a 60 degree 3800...

          Offset grind the crank +.25" then bore it out .030" and there you go.


          and Yes, i have a old 3.8 torn apart and have looked. It's completely different.
