I got my car dyno tuned yesterday and he ended up gettin 300.6 hp and 342.1 ft/lbs. at the rear wheels. I have a k and n filter, a bbk 62mm throttle body, longtubes, off road h pipe and magnaflows and now a tune. I was just wondering what else could be done without rebuliding the bottom end to get it to about 350 hp at the wheels. And how many horsepower aftermarket cams would add? Thanks for the help!
