Normally, I start with the squirter, if you have any kind of motor the factory sq. are too small.
On my 421 we had 42s.
Usually the cams will not need tuning, unless you feel they react too slow, but it normally will be fixed with the sq.

Total timing should be set at whatever RPM you want to have all your timing in it, 3000 RPM is usually a good RPM to set at with a bbc. If it has a stumble when you mash it the secondaries could be not opening right away,or too soon.I would check your timing make sure you got it where you want it then start messing with jets and squirters.
