I'm getting mixed answers for this. So if there is a good reference chart for this please give me the link. But my question is I purchased a conversion out of a 2005 Chevy truck 5.3L and auto trans from a wrecking yard. This is all going into my 72 Buick Skylark. I'm getting ready order from spectre a cold air intake system for it. They list 3 different ones, one plain, one with blade AFM, and one with in-boot AFM. So that's what through up the red flag and don't know if I should have a AFM(air flow meter) or not.. I did not get one from the wrecking yard with this supposed "Everything I would need" package. Any help would be great..

I suggest getting the 5 pin one that matches your truck engine (has screen on front and blade through center) for stock/mild application. you can use either of the 3 but you will have to let the person doing your tuning know which you have. Or you can say f it and not run one, using only speed density which is harder to tune for some.
