Be careful with large generalizations. Velocity is based off of intake and exhaust gases moving due to pressure differences in the engine, valve size and the port sizes more so than cam lift. If anything, cam lobe overlap (LSA), head port sizes and cam duration have more effect on TQ and HP than lift. More lift will allow those gases, especially in a 6.0 or higher, to exit more efficiently.......With a 317 head (im guessing that is what your running) you will have a 227cc runner or similar with a 72 cc chamber. Your TQ numbers will be highest with the cam with the least overlap within a lobe profile.

My only reservation with going with the 224 is that it is considered the perfect sized DD cam for the 346, so you'd think the 228 is perfect for the 364. The 4.10s will take care of my low end with 6.0L grunt, but I want it to pull like raped ape up top.
There's something wrong with my valve events. I am just waiting until spring to prove it
