Can I get away with running the stock 55mm maf with a T. Moss ported stock lower and Thumper head combo, or will I run into lean afr and driveability issues due to the additional airflow? I realize the stock maf is a restriction, and would like to go with a larger one at some point, but I've come up with more questions then answers when doing searches on which brand/size to go with. I'm building a stock shortblock based on a 91 mustang. Stock cam advanced 4*, 1 1/2 long tubes, intake spacer, 12*timing, cold air intake and 65mm tb are the only other mods I'm considering for now. Thanks.
