For those not already into the money end of the coversion, you may want to check out the early Lightnings. No mass air needed, and plenty of tuning available.

My '95 302 is mass air, but there isn't a chance I would spend the money on the conversion unless I was going forced induction, and then only maybe, and only if I was planning on running 15+ lbs of boost.

 

my conversion cost less then 300 with two new o2 sensors
