Posting this for interesting discussion and nothing else........................
So a guy builds a pair of nice 10:1 pump gas 540 long blocks for a pretty nice 33' cat.
The boat owner dresses the engines, stabs the distributor, puts his own fuel system on etc. installs the engines. Engine builder tells him to run about 34 degrees of timing.
Third time out burns a head gasket in one of them.
Engine builder goes over with his timing light and finds 60 degrees of timing 35 degrees of initial timing and a 25 degree advance bushing in MSD distributor.
The engine owner is wanting to know if the engine builder is going to "stand behind it"
