As with the PORSCHE 924 and 928, these cams must be nitrided to avoid premature wear. The factory used the same casting numbers for different grinds. The numbers below refer to the grind not the casting.
MANY OTHER ELGIN PERFORMANCE GRINDS FROM 256-288 DURATION AVAILABLE FOR BOTH 2 AND 4 VALVE ENGINES. CALL FOR SPECIFICS. WELDING IS OFTEN REQUIRED.
