I am looking into a 383 stroker kit for my lt1 and my question is would my comp cam 503 be a good cam for the stroker kit or would another cam be a better pick? And right now the heads have the upgrade valve springs for the cam

No it's not really a great choice, it would be a VERY conservative cam for a 383, it would have stock like driveability and be very torquey from low rpm however. I have the lunati voodoo 60122 231/239 cam and most here would call that conservative for a 383, it has very good driveability....more important question is are these heads ported? If not, 383 stroker is not going to add significant HP, maybe 20hp....just more torque. I'd get a cam similar to mine if you want mild....or bigger if you want to spin it to 6500+ RPM. Are emissions a concern at all? If your heads aren't ported, just get some ported heads and skip the stroker kit, otherwise it would be like a truck motor; all torque and disappointing high rpm HP. A 383 needs to breathe...as in ported heads and healthy cam; and don't make the mistake like some on here and leave the CR at stock, you want 11:1 MINIMUM.

The 503 is too small. Would definitely rather have something in the 23x or 24x range for duration. And like he said, untouched stock heads are not going to feed a 383 with the right cam.

Agree with the above. Since this gets asked all the time, what "kit" are you looking at? If it has a cast crank and junk pistons please step away imediately. Getting your heads done and a nice cam on the stock motor would benefit you more than a budget 383.

Get a set of nice heads, set it up for 12:1 compression with flat top lightweight pistons, and do a cam with intake duration in the mid 230s.

What's your compression ratio gonna be?

Proper cam selection is predicated MORE on static compression ratio than on cubic inches. If your static compression is gonna be in the 10.8 to 11:1 neighborhood, then the 503 cam is a good choice.

BUT.....I'd prefer a cam with a bit more lift if the heads continue to build flow into the .600" to .650" range.

This is what I'd do.

yes the heads and intake are both ported and I haven't look hard into what kit I would buy. Any idea on a good kit?

What's you budget, intentions for the car and long term goals? You certainly want all forged parts, the prices range quite a bit depending on quality...Check this site out, Scat has some budget oriented forged rotating assemblies, or you could spend double that or more if you have bigger goals for the car than most. I'd aim for 11.5:1 CR or better.
