Default pulling vacume???

i just got my car started with the new 383 and its just a handfull. The car is pulling vaccume bad. What all could this effect?

P.S. i still have the ls6 intake manifold so i know i need to up grade that along with the injectors.

By that I mean its not getting enough air. It hasn't been tuned yet or scaned for problems. Its just a full built 383 with ls6 intake and stock fuel system. The fuel pump and wiring harness are being changed today, but the injectors and intake are going to be changed in about a month. Is it going to hurt my engine to drive it when its not tunned and getting enough air.
