[Shotimes] MAF connector question

Unfortunetly no.  This is why installing a 80mm Ford MAF (originally found
on the Mark VIII IIRC) usually results in the car running lean. The MAFs are
generally calibrated to the engines injectors and amount of cylinders.  In
the SHO's case, it is the only Ford V6 to use it's injectors, which are an
odd size to begin with.

I much prefer a MAF like a Pro Flow that is calibrated to work with stock
computer settings, than a MAF that requires the EEC to be re-programmed.
