My dad and I are working on updating the 86 astro, with an L31 crate motor and a subframe from a junker astro that was abandoned behind where we work. We aren't looking for neck snapping power but definitely hoping to pep up the spirits of my dad's baby. So far it has pretty much been prep work, but the time is drawing near for the fun to begin. You can see pics and our progress here:

255 hp @ 4600
330 ftlbs @ 4000
A big improvement over the stock 130hp
Tell me what you think.
PS - Those are my father's "funny" captions under the pics. I suppose we all have a family member with said sense of humor.
