Which cam button would be needed for this and would I need to use a thrust bearing between the timing gear and the block? I would like to use a aluminum timing cover as well. It will be going into a SBC that will be stroked and bored to 388.

Asked by: Bill P
A standard small block cam button is all that is needed for the Comp 249-K12-407-8 cam kit. A thrust bearing is always a good idea.
