UPSMT280Z Posted September 27, 2009 Share Posted September 27, 2009 I live in Montana and have a 78 280 with the n47 head not sure what block but i think its what ever is stock . The car runs good now but i want a lil more umph out of it. I know turbo is the way to go for power but i want to keep it NA for now anyway. What cam specs should i use (id like to keep the stock efi if i can) and also ill either port and polish the head myself or send it out. Any help is greatly apreciated.
