Comp cams xe268h for 318

The truth is I broke my Hughes HE3037AL in with fully assembled 1129 springs. But I did some oiling mods to dribble oil on the lobes, the engine was oil-primed, and I had everything set just right, so that when I hit the key, I just sat down for twenty minutes and had a beer. HUG1129s are pretty stout springs, allowing my .549/.571 cam to rev to over 7200 without drama of any kind....... and since it can do that, guess what, I go there as often as I can.

Your results may vary............
