Rated 4 out of 5 by from Good cam! I bought this cam & lifter set a couple of years ago for my son's first engine build. The engine was a sbc 355 c.i. with 10:1 static compression, mildly ported iron heads, Edelbrock Performer RPM Airgap intake & Edelbrock 750 cfm carburetor. This camshaft made surprisingly good horsepower & torque in a heavy 67 C10 truck with 3.70 gears. I would have given a 5 star review if it weren't for the lifters. The lifters were noisy & 2 of the brand new lifters collapsed.

Rated 4 out of 5 by from Just what I wanted. The cam kit is just what I wanted, not real radical but a noticeable HP gain and a great sound. The only problem I had with the kit was, there was no cam lube enclosed as advertised.

Rated 1 out of 5 by from 268h cam kit I bought the 268h cam kit and went through all the proper prelude and installation requirements. Set preload per recomendation. Several lobes went flat in the first hours of running All done per comp recommendation. Never had one fail like that in all my years of building my own engined. Won't be buying any more comp flat tappet cams. Don't waste your money or risk ruining you engine with glitter from these sorry cams. Just my 2 cents
