170whp is very easy to get you dont need to swap cams ... a set of adjustable cam gears and bolt on`s will put you past 170 with some tuning with cams a little bump in compression and a 2.5" exhaust and a 4-1 header with 2.5" collect on it with tuning would put you up around 200whp and by the way its not all about the peak hp you could have 200whp but it could be peaky and end up with a power band that only last a 1000 rpm or so so a 165-170whp car with good tuning and a flat tourqe curve and a consistant hp curve will be faster
