^^Please see first post. He desires to push it to explosion.
I've found with e85 you can keep the spool values very lean but at WOT my cars loved tons of the corn. 10.8 is what the vette loves, while 11.3 seems to be the sweet spot for the dsm. This combined with slightly less aggressive timing I think will save that stock shortblock (hey it's working for the vette).
I wouldn't hesitate to try both though.
