New 416" street/track motor just fired up! (pics, vids, specs)
The inside of the block was completely die grinded to smooth remove any casting flash and improve oil flow back down to the pan. Corners rounded and small contoured obstructions leveled. Left it slightly rough to get the Rustoleum paint to adhere corectly.
Smoothed access to the drain holes. Smoothed path of oil to the back of the valley. -Got to feed oil to my Milodon oil pan.
