thanks guys for the info. i have a friend that has a trans am running 550hp at flywheel. its 85hp more than what i want and his car is streetable.its a daily driver to his job.man this car has no traction without the slicks. he took me for a test run just around the block and its very fast.here is a link to a camaro running the 12370847 cam in it. its sounds good but i think his exhaust seem to be to small. i dont know camaros always sound funny at the tail pipes.here is the link http://www.madz28.com/chris847.mpg . does anyone have a sound clip of the hot cam. and at what hp?
