i was looking into getting a cam for my lt1, i really like comp cams 306 and 503, how bad would those be for a DD i know they both idle 1800-5800 rpm, what else would i need when i install the cam besided the roller rockers ?

 

You need to get the valve springs that go with the cam.

 

i heard its good to get new push rods if you put a big cam in, would that be a good idea ?

 

You can, and depending on the age of your engine it could be a good idea, but it's probably not a necessity because it has a full roller assembly.

 

id say valve springs, lifters, pushrods, and it also may be a good idea to put in new rocker arms as well

 

how many pushrods does the lt1 have ?

 

One for each valve, or rocker arm, or valve lifter, or camshaft lobe.

 

so are you saying that each valve or rocker arm or valve lifer or camshaft lobe is the same thing just different type of part ?

 

They aren't the same thing...but they come in the same numbers.
