6.4l budget build….kind of
Nice. I like the "no springs" ability. For what it's worth, the stock 6.4 SRT cam might be a little bigger duration wise but lift seems pretty comparable.
Here's the spec's I have for the SRT 6.4 cam.
Adv duration - 286/288
0.050 duration - 221/225
Lift - 0.571/0.536
LSA - 114
Note that I find specs all over the place so I would take them as a general idea. The fact that Summit cam doesn't need springs follows that it would be smaller to a degree.
Not a fan of locking the cam phaser, but I would guess traction won't be available either way so not sure it makes much difference.
