Overcamming is one of the oldest and most enduring mistakes in hotrodding.
As stated, bigger is not alway's better. People have run in the 11.xx's with the stock cam, the 227, 211, hotcam, the 503, 847 etc. all on stock heads.
It must be the sound...

cc502 or lpe 211/219 or lunati voodoo 60121 will run with any of them for daily driving with stock cubes/heads. If you go any bigger it will start to want a stall.

The 503 should get a place in the cam hall of fame but imo to help it around with the surging etc it will want a 2800 stall.

I have pretty much had all the cam sizes. I have had the lpe 211/219 cam the gm846 the gm847 and now I am running a custom comp grind that is 240+. I ran a stock stall until the 846/heads killed the trans. Then I went to a 3000 stall and it was worlds better than the stock stall much easier to drive that way and didnt seem like it was always in the wrong gear. With the stock stall it would want to pull pretty good through stoplights and braking was hurt by it trying to pull through the dinky stock stall. The one I have now likes a 4400 stall and 3.90 gears. The stall covers up alot of the uglyness and bucking and surging that comes from a big cam. The gears are to make the stall seem tighter driving around.

If you stay to a smaller cam and you can avoid the "i want a lumpy idle" nonsense. Then you will do well to stay with a moderate cam. It will have all kinds of increased power and none of the bad that comes with a cam. The small cams are suprisingly fast because of the very large gear splits in the 4l60e and they have loads of tq when it hits the next gear. It is not really an issue with people like me who have a big stall because the stall will give you shift extension and the rpms will never drop below 5k during a run.

Cliffs notes: cc502 or lpe211/219 or voodoo 60121 good to go.

Get a 503 and then down the road if you like get your heads ported for a few more hp... I've had the hotcam and the 503 now and the 503's street manners are similar to the hotcam. JMO.

When these gentlemen are speaking of a stall they are talking about a stall torque converter. What this will do for the cam swap is allow the engine to rev to the designated stall point reaching the maximum torque multiplication, this allows you to take advantage of the maximum torque output of the engine. Also it will allow a cammed car to idle easier as the stall will not "rob" as much power at idle allowing the engines' rpms to rise and fall without stalling.

What gears you have 2.73 ? This is combo I started with hotcam replace 2.73 with 3.73 gears 3.73 made it work well together. When you can add some head work and a bigger cam later, but this combo is good on gas also. For a daily driver this is a good starting point.
