A PAIR of ALFA ROMEO V-6 CAMSHAFTS. V-6 2.5 - 3.0 Reground and "Parkerized" black finish. Lift is appoximately 9.7 mm intake and 6.8 mm exhaust. The specs of these cams are somewhere between 3.0 (9.1 mm lift) and "S" (10.0 lift). Marked 5416, 438 and CT393 (Cam Techniques). Most likely Cam Techniques in Connecticut did the reground on these. Look closely at photos for details. CONFIRM these are what you need using lift measurements and photos! Thank you.
