If i had more money and time (which i don't, so this won't happen soon...), i would want to try the GM/chevy "122" engine. This came largely in the J-bodies from 82-ish to about 2003.
But remember, it also came in the s-10's for a while, so you've got plenty of RWD transmission options.
There was a turbocharged version in the sunbird for a while which made 150hp, so i'm thinking 200hp shouldn't be a stretch either super/turbo or N/A.
Iron block / alum head. i don't think there was an alum block (although not 100% certain). i think around 300-320 lbs.
