Poll! Did you Spin a Bearing after your Cam Install?
I haven't found a poll like this, so hear goes:
I searched, and found people who have spun bearings, but I'm wondering if I can find out just how common it is with a cam install.
So if you have installed a cam in your LT1, have you spun a bearing or not.
If you did spin a bearing, any details would be good.
If not, how many miles do you have on the new cam, and what abuse does it see in your driving style?
Thanks,
Dan

Re: Poll! Did you Spin a Bearing after your Cam Install?
this has been beat to death
what spins bearings is a poor quality install generally speaking
or a cam is installed after some other engine problem like blown head gasket and in reality the bearings got trashed or made very weak by overheat or coolant in the oil

You always hear about the people that spin the bearings, but no one posts just because they don't spin a bearing so that blows it way out of porportion jfyi. 
And no I didn't spin a bearing yet, ~1500 miles after the install and I don't exactly baby it.

Re: Poll! Did you Spin a Bearing after your Cam Install?
3,500 hard miles and no problems yet. I do notice more engine noise
that I think is attributable to the LT4 ED timing set, but I'm not sure.
I only notice the sound at idle and it's a very subtle yet noticable sound.
Not a rocker type sound and not a gear type sound, just something that
is different, that has been there from the moment I started the car with
the new parts.
I was very careful and clean during the cam install. I did notice a bit more
metal dust on the magnetic drain plug after the first 2,000 miles, but nothing
shocking. I'll let you know if I see anything alarming at the next oil change.

Re: Poll! Did you Spin a Bearing after your Cam Install?
I installed the CC306 in with 82k on the motor, also switched to cloyes t/c, elec. w/p,headers,RR's blah blah, at the same time. Very carefull with install,no probs. at all (done a few before), car fired right up and ran perfect. I drove it hard for bout 500 miles, then boom! Spun every single bearing except for the no. 8 rod, including the mains. Now;the car seen 7k rpm shifts several times after cam install, it was still pulling so i stayed in it. I'd say thats the main prob. with my "misshap" anyways, and i've noticed alot of others shifted alittle higher after cam swap. I also blew a head gasket bout 50 miles after cam install also, and the car got REAL hot twice. Motor also had prob. 20 bottles of 150 shot sprayed before the cam swap, so the motor wasnt baby'd by no means. But i've heard of alot of people that spin bearings on low mileage motors, and shift at 6k or so, who knows, just another f-body mystery

So, at this point in the poll it's about a 25 to 1 chance that you won't spin a bearing with a cam install. Sounds pretty good to me. Plus, the one that did spin a bearing saw some serious abuse.

Re: Poll! Did you Spin a Bearing after your Cam Install?
Spun SOMETHING 2K after cam install and 200 after heads ported.
Car/Engine had less than 7k on the clock. VERY easy miles.
Work done by so-called professional mech with so-called excellant reputation.
Decided not to use them again after the install of new short block.
Why the engine went to hell is a mystery to me and will remain so for eternity.
