I am going to change out my intakes from 5.0 to cobra u/l and going to a bbk t/b 65mm. What do I need to do with the maf or do I have to take to a dino or will it run like it is. Also how do I adjust my timing with out a light. Thanks
An intake swap won't adversely affect things to the point of changing the meter so it'll run as is.
It's not advised to do a timing change without a light but if you must, before loosening the distributor, scribe the base of it along with a reference point on the block so you can see how far you turn it. Then, looking down from above you turn it clockwise, turn it about 1/4 inch, that should get you around 2 extra degrees of timing. But as soon as possible, get a light or borrow one or go to Auto Zone and use one of theirs to check it and reset if necessary.
