This thread is really interesting. Having changed cams in my Chrysler big blocks many times I can assure you that cams make as much difference as anything else you can do.
You guys don't really think that the car has the same cam as the regularly aspirated engine do you? If it did it would be a tremendus suprise, and complete dissapointment to me.
After all, an engine is just an air pump spurred on with fuel. When you make the pump more efficient, you make more HP regardless of whether it's naturally aspirated or not. Setting up a dual cam engine is no walk in the park, heck, it was hard enough with a single cam motor but the results were always spectacular once the job was done.
Of course idle is affected. When you change lift, duration, timing and overlap things are going to be a lot different. The change in driveability comes with just how radical a cam profile you use. I had a dual profile in my 69 Road Runner that was way too big and the darn thing wouldn't idle below 1650. But, when you hit the go button you really had to hang on. And really, isn't that what some of us are looking for?
I hope sakigt can find the SRT thread. It would be really interesting to see what's up. Anybody have a "friend" at crane for some other insight? How about at Chrysler?
