1999 454 Mpi, what should the timing be set at?

32*

that better be total !

it should be 8....

8* initial. Thank you.

It is total. 8* initial and 24* advance.

I've been told, on the same engine, that I can change the timing to increase top-speed performance. Say... for a particular event.

Any truth to this?

Better up your octane!!!

You have to put it into base timing mode then set it to 8*.
