    Comp High Energy 270 cam, .516/.516 lift, older cam grind but never was run, got it and new lifters in a trade.

    It's going in the Stepside... hopefully before the next Big Al's Mud Bog. It's almost ready to put in. Started pulling the other 454 out. I'll be gone for the next week though just about, so won't get to work on it and finish it till next week.

    Yep, 23rd and 24th

    I hope it runs good. I had essentially the same combo in my GMC... these heads with 2 other shortblocks. One was .040 over and the other was .060 over, both using a Comp 280 duration cam, with .520 lift. Only problem is the bearings seized in the .040 over one and the rings were shot in the .060 over one. So I didn't get a chance to run either for very long but for the short time I did it seemed like the combo put out decent power.

    This time I decided that since the 280 cam had been run in 3 different motors, it was time to retire it. The 270 is just one step down, and this older grind has almost as much lift at .516 vs the 280s .520 lift. I just hope it holds together.
