i do believe also that the original crossram intakes were made
from magnesium too. which is lighter then aluminum. not a 100% on mag use though



All Max Wedge Cross Ram Intakes were aluminum

1964 Hemi Cross Rams were aluminum

1965 & 1968 Hemi Cross Rams were Magnesium. Some 65 Hemi cars might have had leftover aluminum intakes but I've never seen a documented example.
