The COMP Cams CS 278Xo-8 nitrided camshaft is an oval-track solid flat tappet profile (NIT 248/250, 108 LSA) specified for Chevrolet small-block oval racing. It is intended for 1/4–3/8 mile fast-track use on 327–358ci engines with about 9:1 compression and a two-barrel setup, paired with good intake and exhaust. The nitrided finish provides enhanced surface hardness where noted.
