318 timing............

I'd like an opinion from someones experience.......fact base is somewhat subjective though........

1972 318, rebuilt (clean up bore).......Edelbrock Performer intake AND Carb (450 cfm)........Mopar purple cam (previous owner does not have the exact model cam numbers.....there were 3 you could use, I think....the car has a mild lope at warm idle with new Comp hydraulics and stock rockers). Full 2.5" to 3" Flowmaster duals w/no crossover.....stock electronic ignition....3:55 rear posi, 3 speed automatic.

Tell me based on what you see here, if you can........ What spark plugs would you recommend for this set-up, and what degree of timing might be a good call?

The car is not used for racing.......only for cruising.

Any suggestions?
