I just degreed a bbc using a race cloyes 9 key timing set.
The zero mark was off 8 degrees retarded!
And almost all the advance keyways in the crank gear made it retard even more!
So just to check it
I put the gear on backwards in the advance 8 degree position that put it right where I wanted it.
I called cloyes, they said they were aware of some sets that were marked incorrectly.
He would have replaced it, but I liked the overall quality of the gears and chain and the tension of the chain, and I thought what if the replacement is the same or worse!
it took using a 4* degree offset key along with the 2* retard keyway to get it advanced the correct amount.
That took a ton more time then it should have.
But at least I know where the cam is installed.
ALWAYS DEGREE YOUR CAMSHAFT!
