CREATE TABLE table_1521 ("Engine" CLOB, "Exhaust Ports" CLOB, "Bypass Ports" FLOAT, "Bypass Boosters" CLOB, "SPI" CLOB, "Tapered Grind" CLOB, "Number on cyl." CLOB)

Is there a tapered grind on the Surestart engine?
SELECT "Tapered Grind" FROM table_1521 WHERE "Engine" = 'SureStart'
SELECT "Tapered Grind" FROM "table_1521" WHERE "Engine" = 'SureStart'
