Re: CAUTION!! About Hotcam and Heads
Is there a difference between an SBC pickup and pan and the LT1s? I had a CC305 installed for about 2 weeks before it spun a bearing, and I was meticulous in keeping everything clean. I did not, however, drop the pan. I just got a new used motor and put in a bigger cam. This time I dropped the pan and put on a new oil pump with a white spring. If this one goes anytime soon due to a bearing failure, I'm parting it out. Too much time and money for far too many frustrations. I don't buy into the core-shift idea, cause I never had the heads off, don't think it was debris, because I was meticulous and the motor was in immaculate condition. I would expect these cars to handle 6800 rpm on a stock rotating assembly, and maybe thats the issue. Would having a bit too much oil help at all? I would be willing to sacrifice a bit of power to windage if it ensures some better reliability.

Re: CAUTION!! About Hotcam and Heads
i have to wonder about the coolant in the oil
when my head gasket went south more than half the coolant went
into the oil pan, i even refilled the radiator to make sure of the problem
and it ran out as quick as it went in , and the car sat for about two weeks
and after i repaired it i never had a problem with a spun bearing.
maybe it was the castro gtx oil?

The first two can be driven around for quite a while with nothing but a little extra tick noise and a loss of power as the key, the last would be alot more noticeable. Usually coolant into the oil making it milky and or water out the exhaust.

Re: CAUTION!! About Hotcam and Heads
dont drive your car you will spin a bearing or throw a rod, or some one will hit you, anything can happen heck i threw a rod with 60k on the clock!!
my guess is going to go toward something getting down there!! you siad it was down for 4 weeks, that leaves plenty of opportunity for something to oopsy!!

Hot cam and ported heads about 3,500 miles ago, no problems yet. 91,500 miles on car. I have made 20-30 trips down the track too. Have had several other problems like opti, wires and plugs.

Re: CAUTION!! About Hotcam and Heads
Well, since the error has been pointed out and this has become a show of hands I'll throw my experience in as well.
I've gone through a couple of cams already and am gearing up for another cam swap... my setup is always changing I've also had the heads off and when I get the time they'll be coming off again. I've ran my stock shortblock up to 6500 RPM on many occassions. So far she's still holding together.
I don't know of any spun bearings from all the local cam swaps either, I've even helped on some
I too believe that it's contamination that causes this problem. A lot of people have done some pretty crazy things. For example, using sandpaper to clean the gasket surfaces You shouldn't even use the abrasive pads to do such a thing!
