Dodge hemi was called a red ram (on the valve covers) and was 241 in 53 and 54. In 55 it was called a super red ram and was 270 cubes. The car in my signature pic is a 55 with the 270. Look for a stamping on the block, on the top surface near the valley pan near the distributor I think. Mine reads D55-3 (thus my signature d55dave).
