Anybody running the '68 4 speed 340 cam?

He said he might advance it too 108 deg with low mechanical compression....didn't define what low comp was. I was happy to get an opinion from him.
The engine is very responsive down low. All I want is a well tuned cruiser which is why it is nearly stock. I haven't got into WOT tuning but the carb tuning is getting close last time that I had it out with the O2 meter. Winter is upon us with freezing temps at night and daytime highs under 50F.
Low cylinder pressure is what he means. That's why the suggestion for the compression test.
