K RIPPER

I want to keep my 03 z/06 as stock looking as possible i feel this car could use a little bit more cam and as headers are nnot part of the plan i was also thinking a cam with a tad more duration on the ex. side would be a big help.Has anybody put a slightly larger than stock can in an otherwise stock 03 z/06 the only additions are variram and a tune and 4:10 rear gear. I drag race this car and looking to pick up a couple tenths .will replace parts necessary to compliment cam(springs pushrods)I realize headers and other mods might be more fruitful but this is what I want to do thanks

a/c man

yes that would do it thunder racing has the old man cam cheater cam check it out sounds stock!
