Sierra Denali Cam Swap Help

Im considering it, i really just wanted the most suitable cam i could get off the shelf.
What Ive gathered is, keep the intake duration in the low 22X, and intake lift in .570-.590, the exhaust im guessing is recommended to have longer duration? Maybe high 22X - low 23X, what about the exhaust lift?
Would it be ideal for maybe a 113 LSA, for some chop?

-1 overlap will have a noticeable chop, nothing crazy but you will notice it. You don't just lower the lsa to get chop, changing LSA changes valve events. If you want more overlap that can be factored in by tailoring the whole set of cam specs. However for something that gets daily driven I wouldn't get too crazy with it.
Keep intake and exhaust lift in that mentioned range for longevity. The difference in power between .580 and .610 in a combo like that is minimal IMO.

I thought with the LSA blower swap, there were issues with the water pump or something, meaning doing away with the VVT was convenient, correct me if im wrong.

I talked to the people at BTR, and Im considering one of their LSA Stage 3 cams, I really wanted something off the shelf for the time being, simply because i dont care for any crazy street numbers. They mentioned that they still recommended it, even though it was going in a heavy pickup, and itll match up with my 2800 stall.

id just go with some BTR dual .660 spring kit and pushrods are gonna be in the 7.350-7.450 Range, but honestly man the push rod length needs to be measured when you get the heads back on from the afm/vvt delete. Assuming you’re gonna be deleting the vvt and afm, I would suggest some Ls7 lifters and ls9 Head gaskets. If you don’t wanna measure for pushrod length I would say a set of 7.375 length pushrods would be just fine for your setup if you’re gonna run the Ls7 lifters.
