1992 5.9 LA Roller Cam Motor Build?

I built 89 318 roller engine, 9:1 comp factory, better heads, with roller set up, ended shaving the head got to 9:5 installed a regrind roller camshaft close specs to the magnum R/T specs advanced the camshaft, 3.55 gears getting 14-15 mpg city driving couldn't be happier. Quick engine lots of torque. So I can only imagine the roller 360.
