What are you asking?

When I drained the catalyst beads from my cat. conv. it made a nice difference. the 14" open element Edelbrock air filter also helped a little.

I still have to install the modifed 472 intake manifold and the rebuilt carburator... that will fix my carburator problem and give me more power/fuel economy also....

But the 2.28 open rear end really has to go...
