What are some good combos for the cc306 or GM847 cams? Are AI heads any good with them? Anyone have a combo like that? I'd like to know the numbers they make too. Also... I have a 94 Z. Can it be converted to true duals? I think the 96 or 97 year had true duals, so if they do does the 94 have places to mount it?

 

96-97 cars have dual cats but not true duals. You can install them on your car and if you would do a search you would find many threads with pics and info on the topic. Good ported heads and either of the cams listed should get you very close to 400rwhp. AI does great work. His products seem to always put out more power than anyone else's packages. A guy off the board named Grease put down 412rwhp with the gm847 and AI's econoported heads, not even his all out port heads. AI is the way to go.
