OK I DECIDED TO PUT MONEY INTO THE Z. IM GOING TO GET HEADS AND CAM FOR IT. THE QUESTION I HAVE IS WHAT IS THE MOST POPULAR COMBO TODAY. I WANT TO GET ABOUT 400 HORSEPOWER OUT OF IT. ALSO WHO SELLS GOOD KITS. NEED INFO

 

WHAT MODS DO YOU HAVE DONE THUS FAR?

 

so far no mods but a hooker exhaust but im looking to alot more than just exhaust i want to get heads and cam and do some other stuff do the car

 

Don't do H/C until you have full exhaust (ie. cai, mid-length or long tube headers and 3" exhaust) and preferrably full bolt-ons...
