I will definately start a build thread, but not sure if i will dyno it, since it will be identical to the iron block build i dynod in june. It will be a 549 cube motor, 4.500 bore with 4.315 stroke. I got to 4.315 stroke by offset grinding my Crower 4.15 center weighted crank to 2.2 bearings. Heads ,cam and intake will be the same. 440-1, 3x intake, Terminator injection methanol, and 285/296/114 .867 and .800 lift using Jesel 1.7 rockers. R&R is doing the machine work.
