Sombody said, to do the Predator right, you need to change the lifter bores on the Hemi block as well. What were they referring to, angle, or spacing? Does the stock Hemi layout work, or do you guys order a special Hemi block?
You don't have to change any of it, but you'll need a center bar lifter like the jesel ts tie bar if your block is 48 degree cam bank angle.
In a perfect world I'd do a 45 degree raised cam, +.5 deck block with the lifters spread .1 in each direction for a total of .2 spread. Going more than that on a stock config block will cause the lifters to hit the center cam bearing.
