I was intrested in buying this cam, It is what comp cams recommend for stock heads. I was wondering what ETs and kind of power people were making with this cam. or if there are other cams better for stock LT1
thanks

 

I like this cam, put it in a friends are a few years back.. Its alittle tame for me.. But we went 12.90@109 with full bolt on's 3:73 stock auto..
It was a fun little cam..

 

I run the 305, great for daily driving and no complaints here. Went 12.66 @111 with it and the mods in the sig

 

You should consider the CC503, a bit more agressive than the 305 and satill decent with stock heads.

 

do you have a idle video by chance?

 

Nope, but I can get one in a few. Just got out of the shower.


This winter the motor is getting ripped appart. I'm still trying to decide which cam I want. I like my low end with the 305 and I don't go over 5k

 

Here are some LT1 sound clips for ya

I think the CC305 section is actually the CC503, just looking at the cam durations listed. 224/230, 112lsa is the CC503. BTW - the 503 is a great cam. I really like mine .

Looks like it should do pretty well with stock heads, after looking into it I am surprised more people aren't running them.

 

Cool - I was just currious because I have a similar exhaust setup. (Eldebrock TES -> SLP 2OTL)

Unfortunately for me, the cam swap is a while down the road.

 

So peak power would go to the 503 then 305 then hotcam right?
The 503 and 305 seem to be basically the same, whats the peak power difference between the two?

 

It wont be much at all, but the 503 seems to be the more popular mid size cam from searching the board. It is not "big" or even "wild", it is a great streetable cam with no ill side effects. You will see a big difference over the stocker.
