Mike, the best answer to your question would be to contact a local shop that specializes in racing.
Starting with a 1984 305 engine is probably not going to last very long for you.
When you remove all the stuff from the car it no longer becomes a street car. Depending on your location, smog testing is mandatory and your car will not pass without the stuff.
