my warmed over 460 gets 12mpg in town, all u need to do to big blocks is throw headers on 'em and a good intake, and up the cam a little bit, thoes big blocks get great millage, that is if u drive the same and keep our foot about of it, and if shipping cost weren't so much, id take that 454 from you
