Is it possable to get a cavalier to have more than 500hp with out a turbo?

yeah, buy a 572 big block and convert it to RWD, if u have a 88-94 visit www.v6z24.com and SEARCH, and if u have a 95+ go to www.j-body.org and search, im a member on both red91z24.. you will never get anywhere near 500 on a NA motor, not in a j-body.
