I am thinking about building a 383 for my 92 firebird. What specific parts do you guys suggest would be best? It's going to be a street car.

 

Really need to define a goal. Power or et track time goal

Most street builds a stock block is good. Find a 87-99 oem roller 350 block. Preferably a local machine shop with good reputation to do the work. Types of parts you use depends on the goals and budget
