MAF differences between 305 and 350?

I was thinking about my car (and how I miss it), and remembered that my mechanic told me that his cousin put in a 350 MAF bc they thought it was a 350 (I'm the one who figured out it was a 305). So, is there any difference since the 305s have 19lb injectors and the 350s have 22lb injectors(?)?

I just swaped the LB9 MAF from my '86 IROC into the L98 of the '88 Vette to assure that the Vette MAF had failed and it worked fine though the numbers differed.

A scan tool would verify that all is well with the ECM.

Yup, I've run with a MAF from a 350 in my 305 and it made no difference. Except that the one from the 350 actually worked, uunlike mine which is shafted Oh well, time for the Wells

350 & 305 take the same MAF.
