605 Cubic inch, Best machine built the motor. Heads are the older MP castings CNC'd by modern, with a modern cylinder sheetmetal crossram. Made 1001 hp 807 pds of tourqe. I still street drive the car, that was the first pass off the trailer on this combo. Tried a couple things on the second pass, and went in the wrong direction. I am excited to try and work with it a little this year and get it dialed in, if i dont sell it.
The combo you have seems to be making great power...I would think there might be a 8 second time slip there with some tuning.
