Well to sum this up shortly I'll be opening another thread for this motor soon but now it's gonna be a 496ci with forged rotating assembly, comp hydraulic roller, lots of valve spring, 850 Holley,........ Going in my 81 Malibu in front of my 4l80. Dropped motor off to my machinist buddy about a month ago to get started. 700hp is the goal and streetable. He said no problem.
