Default Re: suspension and ignition setup need help

There are a lot of folks on here that could help you, but I think they would all need quite a bit of info about your combo. 11.22 is pretty stout on redlines, and is at or below the index for your 66 with any engine except the aluminum head 396/375hp at 11.20.
