slant questions

well i suppose i will have to join slantsix.org. i will be doing all the assembly and tuning. i want to make this motor fresh and free of concerns so that my wife has no worries driving this car. since a very mild build probably wouldn't cost any more than a straight stocker, i don't have a problem doing that. however, this car needs to run smoothly, run cool, and stop good so those are my primary concerns. also an upgrade to A/C would probably help my wife enjoy the vehicle a bit more haha.
thanks guys for your suggestions, keep em coming!
