I am trying to spec a cam for my build. I am getting trick flow heads as well. What is the biggest cam you guys are running? I am not to concerned about a little low end bucking/surging. I am coming from a LS7 that had a 248/256 cam. I am not sure how big I can get away with on a 6.2 liter. What size big cams are you guys running? Any feedback would help. Thanks.
How big of a cam???

I too am running a mild cam and have a slight lope at idle. The one thing I notice is the reduction of bottom end torque but increase in mid to top end power. Instead of the cam, I would stay with the stock cam and add water/alky injection instead. You should be able to get the same mid to top end power by having more spark advance and maintain the bottom end characteristics. just my 2 cents
hows your low end take off with this cam and low speed driveablity?
you chopping it up slightly pulling into parking lots?
My cam is .610/.623 at 119. Enough to make the car shake, but not too nasty. 223/[email protected] .050 and 273/289 at.006.
The HPE 700 has a Comp 275/279, .584/.591 @.05 226/230 at .116. Nice lope at idle, especially when cold. Open cutouts really ad a nice dimension (Corsa Sports sound good too).
Beyond that, nothing noticeable other than gobs of power.

Ok... i have my cam card... what the hell are we talking about? What #s are we looking at?
----------
Duration?

Duration?
Lift, duration, lobe separation.
.480 lift 240 duration
----------
109 lsa

So what do those #s mean to me

I think those are correct. Id put the whole cam card on here but the mobile app is a pain in the ass to upload pictures with.

Lift can't be right. 480 lift is like the old days before roller valve trains. Should be580+. The 109 would lead me to believe you have a stick vs. auto, correct?
Yes. I have a manual.
----------
What does that mean then?

It says lift at valve 624. Is that what im looking for?
Yes. That is a reasonably high amount of lift IMO. Not a bad thing unless you are a valve spring that doesn't get checked for a long time. I run a bit more lift but I will have my springs checked every 20k miles.CavemanB52 said:
Ill have to look to see what kind was installed but i had my whole motor built from top to bottom by LMR
Would really like to see the cam card. Those numbers indicate you have +22º of overlap. That's way too much for a street car, especially with a supercharger. Your car will be like a paint shaker at idle.
Its not. You can hear the cam. But its not crazy

Well id show you the card if i could get it on here
