Question about Cam differences

[67pro-street]

I have a 383 stroker engine and i wanted to put a larger cam into it. i was just wondering how i figure out if i need a solid type cam or a hydraulic lifter type cam. is there even any difference and what are the pro's and con's to each type. Also, i was wondering what else i have to change if i put a larger cam in. im pretty sure i will have to get different length pushrods, but will i also have to change the rocker arms and springs and the timing chain etc.


thanks,
