340 dog out of the hole/no low end torque??

those cams correctly matched work great, and for the nos question I can tell you from experience if the heads have been worked good giving that lower compression 340 a lot of air flow it wll love nos mine picked up almost a second in the 1/4 on 150 if the heads are out of the box, that is a little of the prob, don't shoot me guys I have a set, my mildly worked j's were a lot faster, but after getting them worked they worked good, also the you loose a point of compression with aluminum heads through the heat dissipation process that why you can run higher compression with them, any way got mine to run 10.60,s spinning at 126 with 150 that nos takes care of the torque prob lol, good luck:D
