If you can get a hold of a copy of Vizzard's book on building the A series
motor, there is a great discussion on air filters (K&N recomended) velocity
stacks (VERY important), intake manifolds, and carboration.
Presently I use stock filters and housings. I'm going to change to K&N
filters and retain the stock base (cause of the velocity stack leadin) or
add the longer velocity stack inside of the filter.
