How many miles is too many for doing a cam swap?

Again, common sense prevails here. Does your car have good oil pressure? Does it smoke? If it seems like it is in decent mechanical condition, go for it.

Well, assuming everything 'seems' in good shape, no smoke, good oil pressure, etc...

I put ime in at 80K and don't have any problems. It all comes down to how the engine was cared for. I know a guy that is putting a cam in his ride and has 180+ on his.

how many miles do you have now?

Do it when ever you want. What is the worst that can happen, you have to rebuild a high mileage engine? If it is going to go, I bet the cam won't make much of a difference on the timing.

I did mine at 124k, no problems yet. Like Studytime said, as long as the motor is in good mechanical condition you should be fine.

Wear should be the deciding factor on if you want to cam it or not... the thing is mileage won't be a good indicator of wear. It's the best we have, but not a particularly good one. One car could be on its last [motor's] leg at 65K miles, and yet another could be in pristine condition mechanically at 185K miles because of a superior maintenance program and better care throughout its life.

LT1's seemed to have the high milage cam swap issue, due to having 2 bolt mains and if the block is used to not having it un fastend after alot of miles.

LS1's are structurally more ridgid, I would have no worries about a cam swap even at a 100k. Just be aware of cam bearings, thats bout it.

if its its over 80-100k, change out the timing chain and oilpump (like 300 bucks as a set.),

you might as well change your pulley($200), tensioner ($125), etc etc... if you got the money get a balancer and electric water pump too...

word of the wise, if it comes off, you might as well replace it with a new piece if its plastic or rubber.


p.s. i took for granted the springs etc, you need to update your springs according to the cam if your goin to be spinnning it that high, i got an ls6 cam in mine, but i let it shift out at early bc i have OEM springs( i never see 6000rpm)

im at 114k and im doing a cam swap in 3 weeks.. my oil pressure is always 55 at idle.. 65 under throttle.. always running good.. not a daily driver anymore either..

but im not going aggressive with the cam... looking in the 220-224 range..with a lift no greater than .570.. because its not what i need

I know one guy who just cammed it at 120k and one of my buddies has 149k on his and its cammed. They both run like the day they were bought.

This poll made my day. I thought my only option was to save up for a rebuild. I'm at 96K and want a cam this summer.

yeah as long as it runs good and has been taken care of (oil change wise) i would not worry about it
