this will generically resemble the father of this project, the Vanagon LHS. not to the letter, but you can sense a parallel intent:
to be located hereabouts-
that aluminum manifold is the signature of the first gen 3.5-- the previa will recieve the second gen 3.5 with an aluminum block and 40 more hp
the previa has a floor that is 6" higher than the vanagon, so it will emerge less above the Previa floor than here.
