354 or 392? Hemi? Questions?

You have to convert it to rack and pinion? There are parts out there I can get a running 354 for cheap with tranny.... What tranny bolts up to them that would fit in a A body?? Also there is no way not to convert to a rack and pinion how much does that cost? Thanks for the info so far... What did you type in to find that how to?? Turbofreak
