Mild Cam vs BIG Cam?
I've been reading and studying about CAM's and there seems to be alot of talk about Mild Cam's for DD's and then BIG Cam's for more HP. I've done some searching but haven't found an answer to what I'm looking for.
I'm assuming a Mild Cam is somewhere around 231/236. What is considered a BIG Cam? Also, what are the pros and cons to a BIG Cam? Thanks for the help!

If i'm not mistaking a big cam will require a higher stall which will take away the street ability. I don't think that is the only pro/con. I'm subscribing to see tho as I am looking into a cam soon as well.
Did me beating you on the dyno make you want to do this? lol jk |

I have a 223/236 59X-60X. I'm not sure where the line is drawn for mild-wild. There was a thread a while back debating different size cams and what category that fall into. As far as stall I think the dyno graph kinda tells you what stall you will need.

Lumpy idle is caused by low vacuum. Basically the engine want's to stall. This leads to drivability issues when putting around town.

Lumpy idle is caused by overlap; low vaccum is a by product of overlap. I would define the cams listed in this thread (so far) as mild. Anything above 20 degrees of overlap at .50 is considered wilder in my book. Approaching 30 degrees is WILD. The cam in my last car (LS 402 stroker) had 26 degrees of overlap. It took a lot of tuning; but it idled and drove good considering the setup (11.7 cr, 5000 stall, 3.73 gears).

Now if you were to narrow it down to say a 376ci LS with LS3 heads, then you can begin define what cams are too big or too small. Generally speaking, a cam will "rock" the power curve with peak torque being a fulcrum if you will. More duration will hurt lower RPM power, while picking up higher RPM power. |

That's a good way to describe it.

Thanks guys for the replies. Great reading APEX Chase's post. I hadn't run across that, not sure why. I think I'll eventually get a handle on this CAM thing. Guess I was misinterpreting what defines a Mild Cam and BIG Cam.
Now I just need to win the lottery!

Pros and cons are, when you get the mild cam after a few months or sooner your gonna wish you had the bigger one. Mark my words. Lol
