My first Restoration. needs help!!!!

400HP is no joke. If that is your plan, you will need to look into building up the transmission and rear end in order to handle the power.

The engine build can definitely be done on a budget, and has been done before: http://www.moparmusclemagazine.com/techarticles/engine/mopp_0003_360_engine_build_top_end_part_4/

Do a search on "Budget 360 builds" and there will be no shortage of information out there. Also, if you give us some more information on your specific car (or the car you plan on putting this motor in if you don't have one already), the more experienced builders can definitely help you with how to do it on a budget.
