Not sure what people tend to like better. I've heard keeping VVT sucks, then also heard keeping it being a good thing. I am no matter what though, swapping lifters out and deleting AFM. That **** blows. But if you have suggestions on the VVT topic, I would love some input.

id also like to state it’s a semi budget friendly build. looking for no more than 550hp, and keeping it as simple and reliable as i can but with meeting a good power goal. you guys know what it’s about i’m not worried

I'd call cam motion and tell them what you want and Answer all their questions. the whole Gen 5 engine cam specs are quite different than the gen 3 and gen 4 engines in terms of power. I've got buddys that run performance shops and what they have learned about gen 5 cam info for different applications is crazy. so I don't even try to give advice on gen 5 stuff. Call cam company and they have cool computer stuff to get you want you want.

I understand that Katech has some type of machine where they windowed a block and observed valvetrain harmonics so the 64x lift cams they have don't beat the valve seats to death. TSP had on there site that LT engines had a known issue with valve seats falling out. It appears it was due to ramp rates and harmonics if I'm reporting it correctly? Big gains to be had with a .65 cam vs. a .525 cam. I hear BTR and Cam Motion is on board too. Haven't checked it out. Food for thought.

I went with a btr cam spec’d out to
210/223, .540"/.540", 111 LSA, 14% fuel lobe. hopefully runs good!

The specs are:
219/232, .619"/.598", 115+5 LSA.
From videos I've seen, it has a pretty nice idle "cam/chop" which surprised me from the 115 LSA. Comparing the overlap of these 2 cams, they are very close with yours having -2.75* and the Tick having -2.25*.
It will be interesting to see how they compare when completed!
