A tune is a must! Without one even the mildest cam will sound nasty, but occassionally you'll think the car will quit. I have an older hot cam which nets 365hp/390tq after tuning. It sounds pretty mild now. I want more so heads and a more aggressive cam combo is in my future.

 

i have the hotcam for it to really run good idle wise is to tune it to idle at 850 to 900 rpms.

 

i think i will be ordering mine this week, if all goes well.

 

so did you decide on a gm hot cam??

 

Mine originally idled at 800 (M6) and now idles at about 900.

 

yeah i work for a chevy dealer so get it should be no problem, and a buddy of mine is a mechcanic so getting it put in is np.
