318 2bbl manifold swap with OE cam - worth it?

i feel ur pain, i just got a used performer intake, a used holley carb, felpro gaskets and then everyone was like u may as well do the cam now. but im gonna stick to the orig plan and just do the carb/intake swap. it does add up quick though...what i thought would be a $200 weekend thing has turned into a $400 couple of month thing! and im not even done with it yet!
