I am looking to do as much to my internals as possible at one time. Lookin at spending 2k-2.5k MAX on parts (I have a friend who is a mechanic so labor is comparatively cheap for me). I don't know if I should change the intake manifold and have my heads ported/polished, or get a bore/stroke, or what. Should I do the cam first? Can I put a cam into an otherwise stock engine, or for that matter, could I used forged internals in one if I wanted to consider using 100 shots of nitrous? I don't really have a lot of experience here. Where is a good place to start on that budget, looking for max hp while still being reliable?
