NO...

The cams in these cars are not a weak link and I did more research than I wanted to cause the cam issue was a big one for me. After it was all said and done, I personally believe that the offerred cams for our cars really do nothing more than give you that muscle sound. I honestly believe that in a year or two, there will be some serious custom cams for our cars but I just don't see that right now. How well will the stock cams hold? Well, JDM has them on a 900hp turbo car spinning 7600 rpm with no problems. Livernoise has them on their 770 hp car spinning at 7400 rpm. Justin Burcham has them on his car spinning almost 7600 rpm, powerhouse has them on their 660 hp car spinning at over 7000 rpm. Get the point...lol

If they are so bad, then ask yourself why all the top cars out are running on the stock cams? The reason is, they are good. The trick is to upgrade everything AROUND them. The cams will hold at high spin just fine as long as you take care of everything else.

Now let's look at cost cause if you thought you just buy the $650 cams and drop them in, then you thought wrong. The only real reason to want cams is to be able to spin your car up but in order to do that, you're going to need valves, springs, retainers, rockers, seats, ports, etc. etc etc. So that $650 quickly turned to over $2500.

Now if you just want that old school rumble, then wanting cams might be your bag, but you certainly don't 'need' them. In case you're wondering, the GT500 utilizes the exact same cams that are in the GT now.

The stock cams vs aftermarket cams are more different than you think. A read on Comp Cams site will help out here.
