you should meet your 210 rwhp mark. the cobra intake is worth a good 10-15 whp. and not sure what custom free flowing exhaust is. but if its a decent 2.5 inch exhuast you should also add around 10 whp with headers, x or h pipe, and cat-back. now the comp cam can be the problem since the stock cam is best in my opionion with stock heads. but i dont see why you shouldnt hit your 210 whp mark. make sure you have a full tune up first to squeeze every little pony you can out.
Yep, doing the full tune up
I'm a little worried about the cam too... I've compared it to a stock 5.0 and it feels like I have less low end. Screams up top though. Oh and the custom exhaust is all 2.5 after the headers, high flow cats and loud ass mufflers.
thats typical for a cam swap with stock heads. you sacrifice your low end torque for upper end power. a set of heads will be a big boost with that intake and cam.
