I am very close to ordering the Michells block. Since Tim at FHO has moved to Florida I was going to buy one of his raised cam blocks but it is over kill for what I want to do and now there is a machining price added and shipping and since I live in Canada have to deal with the Boarder into Canada and Duty and shipping across NA. I am not going to race this thing, those days are over as a weekend warrior and it might see the track just to see what it will turn in my Challenger in street form but will not be a regular at the track. If I was going to Drag Race again then the KB raised cam block would be the one of my choice if going racing with 1 inch lift cams and super high spring pressures using a Stage V race head. But this is going to be a big cube and really not that big only a 572 street fun motor.with a lot less cam shaft and spring pressure so I dont have to live under the hood every Monday to Friday.
