That is from a 1973 American International 1110 workshop manual.
There is a bit of discussion on the International site saying if the 345 is pushed to 3 deg BTDC they are prone to overheat before any detonation is evident. Like all discussions there are people for and against.
Here is a bloke showing how to time a 345. He suggests maximum 5 deg BTDC.
This bloke says 8 deg BTDC but it is on a Scout which consistently runs higher revs than a truck.
These came out of my international workshop manual , these should be relevant specs for a 345 Just remember that when you time the engine with a timing light the pickup must be on cyl 8 , cheers , jim.

Yes the correct cylinder is number 8 not number 1 like every other V8 in the world , remember I have one too , I timed mine on number 8 the other day and it’s running perfect, Here is just one example below cobba
