The air cleaner on my BBC 454 is a backwards facing, kind of rounded triangular cleaner with a mesh screen on it. My questions are: what kind of air cleaners are required for marine use when the motor is exposed? What does putting an automotive (like a round K & N) with a washable element in it do? Are there any advantages to using a venturi (?) bowl without a tunnel ram, but rather just a standard rpm edelbrock manifold? I understand that the cleaner is probably facing backwards because of the potential backfire hazard, and also to keep water out. Any suggestions would help. -DD out
