I'm building a 2004r to go in my 91 (I know, not direct bolt in) what needs to be done to make it tough? unfortunately, it's not equipped with the grand national valve body, the trans was behind an olds 307, not sure what kind of car though. it'll be going behind an l03 for now, but I plan to upgrade to something a little hotter (alot hotter) but not more than 400 ft lbs.


any help would be appreciated.

Thanks-

Eric
