Just looking to see if anybody has used a holley efi or any efi system on an mv404 or 446 .. What what their results we're. Any improvements in mpg at all?
I'm tossing around the idea of throwing one on my 78' loadstar 1700.
Just planning for the future thats all. Nothing going bad with motor yet but you never know. Looking at my options for a motor with part easier to get. I'm even looking at maybe diesal. I hear the easiest would be a 3208
