I am in desperate need of the cam journal specifications on the ls1 blocks. There is a possibility that mine have been ruined due to a cam bearing coming completely detached from the block while running. All information regarding this will be greatly appreciated. Any machining guru's out there?
P.S I have tried a chevrolet dealership and have got very little cooperation from them

thanks again, Corey

 

have you tried an auto machine shop? they usually have access to that information.

Camshaft bearing journal run out should not exceed .025mm (.0010)
Camshaft bearing journal Diameter- 54.99 - 55.04mm (2.164 -2.166in)
If camshaft is less than spec it needs to be should be replaced.

Thanks
