Want to do 408 but need some help

:D Well im sure tons of these questions are asked daily but I have specific questions that I would like to accumulate answers to in one place.

I want to build a 408 and stick it in a fox body (didn't see that coming huh?). I would like to put in a built c4 tranny and run stock ported and milled heads. Finally I would like to throw 150-200hp shot of nitrous at it. Thats what I want, is it possible? I been looking and I found a tranny that is built but would it slide right in? I have a machined block and want to get a forged stroker kit and I found on ebay. Then the kicker, since heads are so damn expensive I would like to try my hand at porting the stockers and milling them, maybe even some larger valves. I would like to run a hydraulic roller camshaft. Although I don't know if the roller rockers will work on a 351 style heads. I would like to make 450-500hp off the bottle and 600-650 on the bottle. :D are you guys annoyed yet? any help would be great, im on a budget because im a broke college student but I would like to have something by summer time to bracket race with my friends. thanks
 
I'm not sure if you are going to be able to meet your power goals with factory heads that have been ported. For a 408 to put down the kinda power you want usally they are equipped with afr 205 heads or canfields. Yes you can get c-4 built that will bolt in you would have to do some research into who builds good tranny's. I have no idea i like 5 spd's.
