I've heard from different sources that the cams help open up power near the top end but make the mid range/low end sluggish. I'd like a smooth usable power band, but want to keep the torque of the KA. This car will be mainly street driven. I was hoping the GTX2863r will spool quick enough to maintain low end power and the cams will help it up top. I'm also afraid that the stock cams will make it drop off near top end rpm's. Trying to find a good balance here. Looking to make ~300whp safely.

Anyone have experience or thoughts?
Those 270 pro cams are way to big for what you are looking for.
If you are aiming for 330-400whp you need only 256 Poncams.
It will be best if you are seeking to not loose low end tq.

I had 256 on my sr20 at 368whp and 350 lbs tq
