Re: Oil with ash help
GM is still selling EOS,but it is under a different part#,and I havent bought it in a while.I use Comp cams break in lube with every oil change.Same stuff as EOS.There are other cam break in additives that are available at speed shops.You need them at every oil change on a serious race bigblock with a flat tappet cam.I run a 427 to almost 8K with 150# seat pressure and never have any problems even with .620" lift.Good luck.
