To be Honest the 512 Low deck I built makes about 150 HP MORE than I really thought it would make, Hrdro roller, dingleberry hone job, 440 source heads ported by me using a toy flow bench [Super Flow 110 ] ,wide ring gap on second ring, 9.7 to one compression, most of the ? in dvw's thread is more about longevity of the build IMOP. all that said ,, I love my Dodge smile Sorry Im sharing in the race section, my junk is Street & sometimes strip. The LARGEST gain I have done was from tuning, also getting rid of a baffled muffler & going to a straight through muffin
