Hi all,

I'm a bit new to big block engines and now I need to check and align the timing in my engine. Just wanted to make sure is this red marked piece supposed to indicate the TDC?? I just haven't seen this kind of structure structure before (..even in the pictures) so just wanted to make sure.

Thanks

line up the end of the pointer and the long line that is tdc.........looks to be a gen 6 timing cover

Thanks!, yes according to the cast number the block is gen 6...

These are nice way to confirm TDC. Theres no guessing.

Some merc engines need to be put into "base timing mode" to set timing.
