78 GMC Royale 26 foot Olds 403 engine
Question: Installing the needed adapter between the OEM intake manifold for the FITECH throttle body to function, will this fit under the engine cover without modification?
Also what header system works on the 403 engine, I am confused on whether the 455 and the 403 used the same part?
