mass airflow

i have a 92 blazer with a tpi 305 in it and was wondering what mass air flow senser you use to just run a filter off the manifold

to run a filter off your intake takes alot of work.You have to change your system to a map system.which means new computer and harness.Also you have bigger cam in your engine the map cant compensate for it like a maf system. also you make some cool ass duct work for your engine.tag me back for pics of my tpi.......
