I went a different route. Installed the E58 motor oil cooler assembly on the 372 in my Barracuda. It squirts oil directly on to the timing chain. Used the same setup on my ‘78 Power Wagon. Never had any backlash in the timing chain. View attachment 1715843901
That is a pretty cool set up. I never saw or heard of it. An "Eccentric oiler and chain" right through the fuel pump bolt. This site is a wealth of information. Thanks Steve
