I think that the spare crankshaft in my garage is an 803. It has been reground but I don't know how much.

I thought this too, however i have done a bit of research on the net looking at compressions i am aiming for, for my engine.
andf at a compression ratio of 7.2:1, the psi comes out at about 106

so 120 wasnt as bad as we thought...
could this be the cause of damage? or isnt it high enough
