My LT4 HOT Cam is noticeable with the car is in gear, but when its idling in neutral or park, it runs like the stock cam. I have stock heads and intake. I'm sure the ZZ4 cam being smaller than the LT4 HOT runs even better!

It's got a tiny bit of a lope to it - enough that it is noticible with a free flow exhaust system, but not "choppy".

Mine sounded like Lee's, it has a little bit of a lope sound to it but it was very nice sounding.

Hey Iroczz3 were you pleased with the lt4 hot cam when you put it in? I'm thinking about getting that cam and finding some heads to match. Thanks

Sorry I don't have the hot cam, just the ZZ3 cam...
But, I'll be swapping in an LPE 219 cam in a few months.
