YOU make a great point as most daily driver street vettes will live in the lower and mid range rpms and max power in those areas is a good choice. However, the 224 cam seems to get it down down low, mid range and up high to and of course we know that PEAK HP number is great for bragging rights and selling cams and motors!:D Can you refresh my memory as to the specs. of the GM HOT CAM again? :cheers:

I sure can, since I've got it written down right here so I can obsess over whatever my choice will be. :D

218/227 .525 112

224/114 with a tune - your requirement to pass sniffer test is why I'd recommend this one - simple as that.

 

after reading all the posts here& at ls1tech. it seems this :iagree: is the 1 to go with,its recommended by ALOT of people,now who has the best price$$

 

I had the hotcam, and while it did deliver good power and sounded like a beast at idle or WOT (or anywhere inbetween), it was not an emission friendly car. With the 218/227 overlap coupled with the 112LSA, the inspection guys were laughing at me as I rolled the car into their bay. That car was totalled last February (2003) when a girl slid into my and my wife's lane head-on. It pissed me off because as much as I loved that car (and cam), I would never get that combination again because it was too much trouble to pass emissions.

Opinions are going to vary, but any cam over a .570 lift will tax whatever valve springs you have installed, which it sounds like you are not looking for. Concerning emissions, I would stick with a 114LSA and don't get too much overlap in the cam or none at all (222/224 or something). I'm no expert, far from, but I do have first hand experience with the hotcam. It is awesome in everyway for a car with stock heads and exhaust, but the emissions were to much of a pain. I also had FLP headers so that didn't help my emissions either.

Good luck. Trying to find the right cam is a fun problem to have! :)

 

I'll be getting the G5X-3 (lsa 114) Cam Pkg. real soon. Decided for security to use the Comp 921 Dual Springs. I was told by a very reliable vendor these springs will be great for longevity.

GREAT CHOICE OF CAM and lsa and SPRINGS!!! THAT Set up should ROCK THE HOUSE!!!! :cheers:

 

Thanks, and 400rwhp/rwtq will surely ROCK THE HOUSE :lol:

According to Scoggin-Dickey, the LS1 Hot Cam is a 219/228 525/525 112. When you calculate the overlap, (219+228)/2) - (2 x 112), you get -0.5 degrees. That should pass if it is tuned well and the engine is in good shape but it is going to be close.

You need to have 0 degrees or less overlap to pass the sniffer and there are a number of cams of various combinations of duration and LSA that will get the job done. One thing about lift is that more lift does not tend to have a negative effect on emissions, just a positve effect on power thoughout the RPM range. Heads, while they can be expensive, also give you power without effecting emissions.

My LS6 stage2 heads and 218/218 563/563 114 cam together with the rest of my mods including a good tune makes 380rwhp through an A4 and when it was sniffed it did not even register at 2500 RPM and was barely above average and well below max allowed at idle.

I have decided to take it up a notch and have a 224/224 581/581 114 on the way. Now if someone who makes longtubes (especially LG) would just make the effort to get a CARB#, I could take it up another notch. And if the longtubes ended up costing more money because of the CARB#, then so be it.
