bearings went out....
 

i have a chevy 468 /9:1 comp/flat top pistons
and the bearings went out
i didn't run it much do you think it destroyed the cam??
there are not alot of metal shavings in the pan
look at cam had it for 1 year min driving on it.
some wear had roller rockers on it

i used a mircrom on the cam they all are the same size!!
is they anything else i need to concider

Are you talking about the rod or main bearings went out ?

Cole

the main bearing ,the crank has .1000 lip on it, a machinist can grind
it right?

I have went in and did just the bottom end without any problems. You will need to take the crank to a machine shop to make to call on it. Just go ahead and do rod's and mains and a new oil-pump while you are in there thats what i would do if everything checks out ok. JMO Someone else might say different, But i have done this more then once without any issues.
How many miles do you think the engine has on it ?


Cole

ok thxs for the reply

Also, to add to what cole said, i would replace the cam bearings as well. Excessive clearances in the cam bearings causes low oil pressure and may have contributed to the main bearing failure.

ya thats would make sence,the lobes on the cam really
arent that bad with measurement

The lobes have nothing to do with the bearings. They are very cheap and not hard to replace. Worth the time and money to prevent another failure.

ok that true
