K12-211-2 - Comp Cams 'Magnum' Hydraulic Flat Tappet Camshafts is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Great profile, nice sound at idle, pulls great I got this kit for my 71 GMC C3500 it had a GM crate motor in it. Manual trans. I wanted more power & torque. So Comp cams cam kit with the 270' duration 470" lift gives me a "smooth" slight choppy idle 700 rpm with 18inHG 10' BTDC Paired with Edelbrock RPM Heads, AirGap intake and AVS carb 650cfm, Herman headers to 2-1/2 exhaust. I still need to tune the carb, needles and jets/ spring kit on the way from Jegs. I will swap out the manual trans for a 700R4 soon as this truck needs another gear! Maybe ring and pinion swap too. I'm very happy with the cam kit as it will work with any of the options I plan on doing later.
