318 replacement cams....
Might be a good reference to meet smog specs. To get a car to run it's best at idle, some of those 67 and prior specs are decent. None of the 68-69 are worth a crap.
Stock 318's run nicely with 10-12 BTDC. That's where they timed them before the smog spec stuff came around.
Throw any 68+ manual numbers out and time the engine where the engine likes it if you want it to run best. Then fix the distributor to hit a total number that is right.
