I like the 256 XE better than the 262 XE here, too. It’s on par with the Lunati voodoo 258/265 (213/220) in post number 11. Either of those grinds will really add some grunt from idle into the mid range. By virtue of the four speed, even a comp 218/.450 268 high energy would work decently, but would be close to the largest hydraulic cam I would use…
