We can still thank the 426 hemi for keeping the brand relevant. I watched all the 481X stuff be hailed as the next thing to overtake the hemi. Now I see them all coming out, and hemis going right back in lol.
Ain't that the truth of it......The Hemi rules in any class its allowed to run in.....I got to view a few of the new 4.9 Noonan ones, and man, that is next level stuff. Hoping that becomes more popular as well as the Goodwin Hemi's..... And I totally agree on the Predator heads.....If they were priced a little lower, that would absolutely be the goto head for bigger power I am sure.

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. My first motor was built exactly like that, 604CI, Hemi block raised cam, 45* lifter angle, 2" spread, 55mm cam 7,4,3,2 swap. It lasted 27 runs as the dopes that built it didn't think an engine needed more than 40psi oil pressure. That was expensive! The right way to design one though was right, less the oil pressure.

Who has the fastest Predator headed door car I have heard there is one in this area that been high 4.40's NA supposedly. If so I would have to expect that's gotta be close if not best NA.
