PONTIAC REFERS TO THE STD TRANS AM ENGINE IN TWO FORMS, THE L74 HO 400 ENGINE, IT IS THEN REFERED TO AS THE RAM AIR III MOTOR IN THE ADVERTISING . USUALLY WHEN PEOPLE REFER TO THE GOLFBALL SIZE PORT RAM AIR CARS THESE ARE THE IV'S. THE III'S SHARE THE STD HEADS AS YOU KNOW. CHECK OUT COLUMN 34 OPTION 8 ON PHS'S FORM'S AND THIS SHOWS THE SAME. IT WAS JUST A NAME GAME. THEY DO RUN GREAT AND HANDLE GREAT. I EVEN HAD ONE OF MINE TO THE DRAGSTRIP LAST SUMMER. THE STARTER ABOUT HAD A HEART ATTACK, BUT YOU HAVE TO DRIVE THEM.
