Must use Kenne-Bell Springs, No Wiggle Retainers and Lifters. OK with stock trans but a KB Switch Pitch really makes things happen. Adequate vacuum to operate power brakes and steering. The crowd will definitely know it isn't a stocker. Idle would be too rough for street use if it was on closer lobe centers. Wide 118° lobe centers make this relatively hot street cam behave much like a smaller cam. Dual pattern ( more exhaust duration than intake ). OK with stock rockers but KB Roller Rockers recommended. Easy on the valve guides and valve train. There is no better cam anywhere for this application. Hundreds of satisfied KB customers who drive their cars daily with the cam will attest to this. Amazingly enough, this unique cam is equally at home on the street. In 1983, Mark Busher ran 10.70's at over 121 mph with the same cam in his "World's Fastest Stage 1" 1970 GS Buick.3 seconds and 3 mph and a good 35 HP over the stock cam. The original 455 "Cheater Cam" powered these cars to 11 second times at over 112 mph way back in the early 1970's. Originally developed by Jim Bell in the Pop Kennedy, Doug Jones and Mike Doyle NHRA drag cars. Excellent mileage.įor 14 years, the venerable KB Mark C118 "cheater" has been the most popular and best-selling performance street/strip cam for the 400-430-455 Buick. Recommended for lighter GS, Skylark and GSX cars and especially the heavier Rivieras, etc ( same cam selected by Gary Bryson for his Hot Rod Magazine 350 Skylark Test Car ).
A KB Switch Pitch Converter is an unbeatable combination with this cam. Idles with a slight lope so you can hear what you spent your money on. Wide Lobe centers and dual pattern for smoother idle ( idles like a cam much smaller than it really is ). All of this without any appreciable loss in economy.
One of our satisfied 455 customers appropriately refers to the KB Mark 2 as the "Grocery Getter" because it offers superb street driveability for the wife ( good idle, low end response, etc ) yet gives a substantial improvement in power and acceleration when called upon. A good baseline is to shift at the upper range and experiment 200 rpm at a time in both directions until optimum acceleration is attained. Best shift points for maximum acceleration is dependent on manifold, carburetor, air cleaner, head flow, exhaust, etc.
These rpm ranges apply to our cams ONLY and if Kenne-Bell Hi Rev Lifters, No Wiggle Retainers and Springs are used. NOTE: Kenne-Bell Cams are engineered to concentrate maximum power and torque into the power range parameters listed above.
