The D-501, 1957, Dodge featured in the February, 2003, 'Mopar Muscle' with the 354 hemi is what they say would have been the Chrysler NASCAR offering for 1957. What engine was this? Was this a warmed up 300-B engine? A picture shows definately a hemi with two 4-bbl carbs in line (and a lot of other strange looking stuff) which could mean that the race engine used the production 300-B manifold or - - -. Just curious. Warren Anderson Sedona,AZ
