I have a question for the ones of you who say the summit (crane) or whatever it is grind is trash. And let me start by saying that I have great respect for you and acknowledge your experience and knowledge. But have you ever actually ran or drove a engine with the cam or you just saying its trash based on the numbers? Because I have read at least 10 or more reviews with ppl completely happy with it summits website has 3. One of them is a 4x4 360 he even commented on how great the low end torque was. So I'm curious have you had a bad experience with it or you just saying its trash based on the numbers on the paper? I get it the ramp like 74 is not ideal for cylinder pressure the 112 lobe separation doesn't help bottom end either but surely it cant be that bad cause summit still makes and sells these things after all these years. There is one video of a guy running it sounds pretty stout to me you can see the car squat at about 30mph and sounds like he is spinning. So like aj said less than 30mph its probably not gonna be set no 60ft records but I'm not racing this car it's a driver. So please let me know if you have any hands on experience with this(these) cam and again this is completely a respectful post.
