My 422 smallblock build

I would add that the hardest thing to cam is a street driven four speed. Despite the differences in all the above cams on the dyno most of them would be within a few hp of each other at peak and in a correctly setup auto trans car would run almost identical at the track. But what about the power curves below peak and how that relates to a manual trans street car?. It needs to have grunt down low,in mid throttle situations and make good overall hp all without the help of a torque converter. That is where for me the tighter lsa comes into play, I have driven manual trans cars with 240/250 @ .050 cams and 3.91s/4.10s on the street and unless its a 455 pontiac the 110 and up lsa gives up drivability over the 108 and lower lsa everywhere under peak torque. I agree there is much more science in the end to picking cams/lsa but as has been proven time and time again if you are close on cam timing there is no big hp gain (I am talking street cars here not every tenth at the track). I will go with the cam that has a tighter lsa for the overall power curve down low in a street car and not worry about the negative effects on idle quality.
