So gonna start rebuilding my motor. Is the hot cam kit from summit a good idea. I want try to get 500 hp out the motor when finished

Sure, the Hotcam is "good". But the kit is overpriced, and the springs it comes with aren't sufficient to control the valves at the revs the Hotcam wants to be shifted at for best performance. You'll want to use the thinner .026" head gasket to boost CR to work better with the Hotcam.
500 hp......not a snowball's chance in hell with the Hotcam. More like 400 .. at the crank.

Then what cam would be good to try to get 500 hp.

Just a "cam" is not your route to 500 hp.
You need to do a lot of reading to get a basic understanding of how this all works before anything that anybody on here says to you is going to make sense.

Ik I'm rebuilding it all, jus trying to figure out what cam so I can order it, then the other parts

Don't be lazy.

If you don't heed that advice, you're doomed to failure. And it will be an expensive lesson if you're bound and determined to order parts now.

Alright, I'm jus worried with the miles in my engine that the bottom end won't handle it

IowaSS

Good thinking. If shooting for 500 hp, you'll need a professionally rebuilt shortblock. Just "rebuilding" it by putting new bearings, rings, and seals in it and buttoning it back up will guarantee that it will go ka-plooey.
Budget at least $2000 for parts, machining, and professional labor to rebuild yours or buy a really stout shortblock for ~$5000 from somewhere like here:

Thanks, I want to keeping the block I have, my thing is finding a machine shop were I am that does good work

The problem with 500 horsepower is the collateral problems you'll encounter. Your rear can't handle 500 HP. A new one costs $2500. Your stock suspension will hop, twist and otherwise not get the power to the ground. You'll replace the lower control arms to the tune of $500. Think that trans will take the torque output of a 500 horse engine? Nope, a high performance build is in your future.

500 horsepower sounds great and it's great when bench racing but you aren't going to build a good 500 horse car for $2000 in parts and machining. Believe me, it's closer to $6500 if you do the work yourself...way more if someone else turns the wrenches.

There are lots of guys on here that can help you with your choices on how to build a 500 horse engine. I just thought you should look at he bigger picture.

First determine your budget, and the vehicle's ultimate use - daily driver, stop-light drags, auto-X, or hard core 1/4-mile.

Are you looking for 500 HP at the flywheel or at the rear wheels?

Are you figuring a naturally aspirated setup or a power adder (turbo, S/C, nitrous) to reach your goal?

Then start with the heads, not the cam.

500 to the fly, not gonna be a daily, might drive to work once a mknth, cuz were in love rains to much and eventually want do the suspension for autocross

Read the link posted in post #4. Presents what you need to do in a perfectly logical progression. Air in.... exhaust out.... beef up the engine components that control the air flow.

You can achieve 500 HP at the flywheel with ported stock LT! heads and the correct cam. You will need supporting mods, like larger fuel injectors and a PCM tune.

In general, unless you have extensive experience in engine building, trying to buy your own parts and giving them to an engine builder can be a big problem. The components have to be carefully matched to the final goals. Or, do you plan to assemble this engine yourself?

I would also suggest you add a "Signature".... evryone here is assuming your "black96camar" is a Z28/V8. We have no idea what trans you have. We have no idea if you have made any modifications to date. You also have to tell us if you live somewhere that emissions testing - visual, tailpipe, or PCM hookup - is required.

I love in Washington and for emissions they hook up to the obd2 port
