Just curious how long most of you waited until really getting into it after a cam swap? I've heard and read different things, so just looking for more opinions

No real break-in needed, except for some who heat cycle the springs, several will install and go hog wild outa the hole.

check oil pressure. look for cops. run the **** out of it and feel the new power. break in done

LOL ... I like those two methods!!!

I let the car idle up to temp, give the springs 3 heat cycles keeping the rpms below 4000, then I drive it like I stole it

I like the idea of it too...
I was posting no break-in needed for the cam, the spring comment, i didnt say much because I didn't know...

make sure to change your oil after like 500 miles, mine had some shavings in it from break in and such...

I let the new springs heatcycle twice. I know guys that let it warm up, and went out and went WOT right away.

Play it safe and run it up to full operating temp and around as long as you want for the first day, never taking it over 4k RPM's. Then, let it sit overnight to make sure everything has cooled completely down in the valvetrain. Then, start er up and let it get to operating temp and drive the **** outta it

ditto, it just takes one good warming and then a few hours to cool...then try to go break it.

Springs nowadays do not need to be heat cycled like they did years ago. Theyre made of different materials now. Its a throwback to when they were made of spring steel, not ultra pure si/cr like they are now. As far as shavings in the oil, you really shouldnt have any of these either thanks to the rollers, assuming that youve cleaned your cam well before stabbing it in the block. The roller cam does not need a break in like tappet cams. Also, think of what an installer/shop would do... theyll install the springs and throw the car right on the dyno to tune it. Theyre not gonna wait out three heat cycles.

All that being said, it dosnt hurt to err on the side of caution. Changing your oil too soon wont hurt the car. Neither will giving the car three cold starts before beating on it. The mental stress of waiting, however, may actually kill you.

I'd get it up to temp. make sure all your fluids are good and then take it out. There is no break in on HR cams. "Break in" was used in the old days when they had flat tappet cams that would develop wear patterns and needed to be ran at high RPM for the first few minutes.

After the cam install, I usually start it up and let it run at idle for about 20 minutes.
Then let it cool off for a few hours or overnight.
After that I just let it get to full operating temperature and give it hell .
