Well for those who understand how an engine works will acknowledge the concept behind removing excessive weight from the rotating mass.
Most popular is the balance shaft delete or neutral balance shafts. Along with lighter Eagle rods, lightweight crank/alternator pulley, etc.
Here is an insight of what the early LG0 consist of. "DOUBLE ROW Chain". A lot on the heavy side so I can either swap for the single row to loose some weight or install Ron's Timing Belt swap kit for the Quad 4 (LG0 and W41 engines only)...will not work on the LD9.
This is the best option to free up horsepower and make the Quad 4 scream beyond the well known redline.
I sold the H.O. Cams including lifters for a good deal.
Just the begining of breaking down the LG0....hope to see her future.
