danielf · 06-29-2009

Can anyone tell me what the stock cam specs are for the 289 non K-code motors are? I would asume that the C and A code cams are teh same but not sure. I keep looking but can not find out what they are. Im looking at cam options and wantto compare the differences.

Thank you.

Hi, I was wondering to the member who replied with the specs, are C Code and A Code cams both the same specs? I am switching the factory 2V to a factory 4V setup and was told I might need a bigger cam. Could you please specify? Would I need a bigger cam and if so, do A Code factory cams differ from C Codes? Thanks.
