I have a '91 camaro RS with a 305ci v8. Is this a roller cam or a hydraulic cam? how hard is it to replace?

Is this a roller cam or a hydraulic cam?
Both... it's a hydraulic roller.

It's not hard for me to replace one. If you're asking such a question, I'd guess it would be harder for you than it is for me. Beyond that, who knows.

Brain surgery isn't hard, to a brain surgeon. But I doubt you'd want ME cutting on your brain. And I'm pretty sure I wouldn't want you cutting on mine either, if I had one.

Pull front accessories, pull timing cover and chain, replace chain!, pull intake (dizzy, and evreything else associated with it), remove rockers, pushrods, and lifters, slide cam out, slide cam in, put NEW chain on, installation is reverse of disassembly
