Cylinder head dyno shoot out
I've had a couple of conversations with Jim at Racer Brown recently. He is waiting on final flow numbers and compression ratios before grinding the cam. Those specs should go to Jim next week. With chamber volumes ranging from 60cc to 71+cc and port volumes ranging from 193cc to 208cc, some compromises will have to be made. The most likely scenario is opening up the TF and the Shocker chambers to 65-68cc range and milling the Bloomers to match. Hard to do a true apples to apples comparison with such a disparity in chamber volumes. Therefore, none of the heads will be truly 'stock', but it's what must be done. Otherwise the 60cc TF chamber would dictate the cam specs. I've been grinding/testing on an extra TF head for the last week. Most of my testing on the ProMaxx is already complete.
@NC Engine Builder is progressing with the short block work. He's waiting on me more than anything.
