What are you using the car for and expecting from this mod?

The Hotcam is probably the best package deal, and the hot cam is one of the best all around cams out there. Good for a street car and occasional trips to the track when you want just a bit more out of the engine. It makes good power in the middle RPM range and will pass the sniffer and still has a hint of a ruff idle. You'll also need to either install an LT4 knock module, or better yet retune.

But in my opinion, if it were my car I would look more closely at the 305-112 cam. It is the next step up, just slightly more duration and 544 lift (1.6 rockers) and will make more power up top without needing to over spin the engine. and can be set up without needing any head work to support HD springs and such. Will definitely need tuning and with a good tuner it will pass the sniffer as well.

Either the hotcam or 305 can make 310-330 HP, Seen a rare few Hotcams go 345 with ported heads.

If you're planning to do allot of racing or are looking for 350+ HP you'll need to go larer. But it's 50/50 if the pass the sniffer?

Anything larger then the 305 you will be getting in the area where gears and a looser convertor will be needed to get the proper responce from the cam, and street manners will begin to change. ( personal preference on what is streetable!) Depending on what you pick you may also be getting into the area where the heads will require machine work for vavle springs ( I not liking what I hear about the beehive springs lately! )
