I was wondering if it would be ok to put a diff. cam in my 95 z28 with 103,000 miles on it, or if it has too many miles to change it out without having to do anything else.

 

Plenty of people have cammed their engines with that kind of mileage. A big factor is making sure you do a clean install.

 

You can... but there are some things to be concerned with. You hear of some guys having no problems and others who barely got 500 miles out of it and they were eating bearings. Check out advance inductions' website. They have a few cars with over 100k on their motors. One had 140,000 plus miles and it was making great power.
I guess if you are going to do it, you may want to have a plan B if it does go wrong, just so you are not left hangin.

 

there is also other things involved when doing a cam like springs that you need to research also.

for the most part i think you would be ok to cam it though

 

As long as things have been taken care of, 100000 miles is not the end of the car as we have known it...It's just a number...

But definitely do springs, pushrods, and all that crap too...

 

that makes me feel better about doing it. is there any one cam that would give me the most power over the rest?

 

your going to get mixed results on this for sure, just do a search

what are you looking for , daily driver? nice manners?

cc305, cc503, cc306. or a custom grind like a LE or AI

 

i drive it quite a bit in the summer, and i'd want it to sound pretty mean at idle

 

I agree. Also there is also such a thing as having too much cam for your heads. Bigger is not always better.

 

what would be a good cam for the stock heads?

 

you're not just buying a cam for the way it sounds, right??? I just wish Freddie was around, he gives the best LT1 based advice of anyone out there...

 

right. im going to get a cam and all of the parts that i need to do it the right way

 

I'm on my 4th cam and 3rd set of heads at ~103k miles right now so you should be fine.

 

sweet. i am leaning towards the cc306 i think its what im lookin for
