KB Hemi block and Predator heads, Bryant crank, Jesel belt, blah blah blah. 596" single 4 for brackets and mainly .90 racing. Should be 1130ish or so.


Also freshening our 600-13(smaller version not the X or 3X) 655" deal. Should both make similar power numbers. Be interesting to see how they fair as the combos are pretty close to each other in terms of cam numbers and compression carb and both being bracket pieces. But one with a "spread port" type head and the other with a typical BBM type head albeit with a much larger intake valve and cross section. One is 69" bigger as well. We know what the 655 made before and this time it should be a bit better with not so much piston to wall and more compression. Hope to dyno them back to back and Ill share more later when they are both done. Should be an interesting comparison.
