I'm not sure which one of these Cam and lifters I want to put in? 73 D100, granny 4-speed, 355 gear, 1 tire fire, 235/75/15.. 318 with 150 lbs cracking pressure, 2 barrel, single stock exhaust... I'm just stabbing the cam in and lifters with a new timing chain and gears.. New oil pump and reseal the motor.. It will likely be one of these two cheap cams from Summit but I'm just back and forth on which one?.. I will be adding power brakes. I'm probably just a direct line from the intake manifold.. Any suggestions are welcome thank you..
