i would stick with the 93 cam. its very aggresive unlike the 94-97 cams. It makes like 45hp more. You can also go with a LS1 driveshaft. its lighter and will give you another 30hp. The stock one is steel

those are run of the mill LT1 heads, however they are one of the more desirable castings for porting but stock LT1 heads none the less. That being said if you want to meet your goals you are going to need heads (ported stockers or aftermarket, or ported aftermarket) cam, rockers, headers, and any other supporting mods I don't feel like typing out

are you even sure you're driving an LT1? lol
you'll need to figure out exactly what is going on with your motor before we can help you.

it is a 93 block with 97 heads it is a lt1 motor i took off the tb an put a carded intake on it from gmpp its going in a 88 monte carlo have not installed yet tryin to finish building the motor before i put it in the motor is originally out of a buick roadmaster
That casting number is unlikely to have come on an 97 LT1, it is an earlier casting number and that is a GOOD thing. As covered in 97 the Vette went LS1.
IMO if you are going to put a carb on it skip the LT1 and just use a gen 1 motor. The multiport injection is a BIG part of what sets the LT1 apart from the older stuff. If you aren't going to use it why limit your parts selection to LT1 specific stuff.
Your apparent belief that lift numbers are all that matter in a cam suggests you learned all you know about engines in the 70s. Also the common cam that has .525/.525 lift is rated with 1.6 rockers already so it is .49x with 1.5s the way most other cams are rated.
Your 500hp goal is a pipedream if you think you are going to do it with unported heads, a stock shortblock and an off the shelf cam. Even more so if you think you can do it with the GMPP carbed intake which I will guess is what you wanted to use.
Basically STOP everything right here and start over. Come up with a reasonable goal, tell us what you have and then maybe we can help you. 500hp is doable, BUT not really on halfassed thrown together parts you stumble on cheap.
Based on performance my engine is likely over the 500fwhp number, ends up costing like $3000 in heads, intake, valvetrain, gaskets hardware etc. and then the stock shortblock needs a few hundred dollars put into it to be reliable at the necessary rpms. Beyond that the car needs a LOT of work, good TC and tranny, gears, fuel system, exhaust. Adds up FAST.
