It was a shootout between the TFS-R, Holley Systemax, and Edelbrock Victor 5.0 with a GT-40 as a baseline. The motor was a 11.5 CR Coast 347 using a Comp Cams Extreme Energy 292H solid roller cam (254/260@0.050 and .621/.627 lift with a 110 lobe center). The throttle body was 75-mm. The heads were milled AFR 185's for the 11.5 CR on 10.5 CR pistons. It utilized 36lb injectors, a Pro-M 77mm mass air meter, MSD ignition, an electric water pump, and 1-3/4 full length Hooker headers.

It's a very hot street motor with the compression and solid roller cam but the Holley boxstock was the best all around intake on this particular combination. For a 302-310 motor, it's good for 7000 rpm unported without the torque losses of the Victor 5.0 or even the TFS-R. It's definitely not the best intake for an unported head street motor. But for a hot cammed, ported head, 6500 rpm street/strip car, it kicks butt. The full article was in the January 2001 edition of MM&FF.
