Other than whatever they have at FRPP, there are only 2 sets of these cams. Justin Burcham has a set which is the one on youtube. The other set is in transit to another shop and I promised not to mention any names.
Anyone else that claims to have them, know when they are being released, or have them on order is either mistaken or a liar. Doug at Sutton is taking pre-orders which means he is making a list of people who are interested, he is not even taking any money yet.
I have no factual basis for this whatsoever but I am guessing from what I have heard that they will be out within the next few weeks. I do know that if I don't end up being the guinea pig with that other test set then I will do whatever I can to get a set when they come out. I know that there is a lot of doubt but I have been assured that they will not require springs, will make 20+ peak RWHP, and will not lose any low end power.
Not looking to argue with anyone, just hoping the rumors are true!
