CREATE TABLE table_70503 ("Year" FLOAT, "Entrant" TEXT, "Chassis" TEXT, "Engine" TEXT, "Points" FLOAT)

Can you tell me the Entrant that has the Chassis of march 742, and the Year larger than 1974?
SELECT "Entrant" FROM table_70503 WHERE "Chassis" = 'march 742' AND "Year" > '1974'
SELECT "Entrant" FROM "table_70503" WHERE "Chassis" = 'march 742' AND "Year" > '1974'
