What’s up, guys? Wondering if anyone has a RKv3 or any RK can running on a lq4 or lq9? I want to get the RKv3 but I don’t know the specs of it and I really don’t want to get a cam without knowing what I’m getting. It’s between the RKv3 or the MS4 cam. Thanks.

 

Well,

Let’s start with what your goals are and what’s it going in?

Neither cam is ideal in a truck.

 

I want 500 to the wheels, but let’s be real here, that is probably not gonna happen. I understand it’s not ideal for a truck. Im not going to use it to tow or anything of the sort. it’s going to be a race truck

 

Cam only 6.0 will not hit 500rwhp

you're going to need a badass top end and a super amazing exhaust to get 500 out a LQ9. I would not use an LQ4 for this unless you don't honestly want 500

through an auto however; I don't think it's happening, sorry.

 

Even 500 crank is a lofty goal with only cam, springs, injectors and a tune. The LQ9 comes 345HP crank and without upgrading with aftermarket heads for better flow and higher compression you're probably looking at a respectable 100hp gain with cam, exhaust & tune.

 

Yeah, I figured I’m not getting to those numbers. Honestly I just want to get as much as I can out of the motor so it can defend itself. I’m thinking of going 408 and turbo later. For now I just want a nice combo to get the most out of it and I heard the RK cam was good, I just don’t like that the dude doesn’t give you the specs. Thinking a MS3 or MS4 cam I’m gonna end up going with.

 

If you want it to defend itself, do this instead:

1. Smaller cam
2. 3600-3800 stall
3. Headers, free flowing exhaust
4. Gears

Those donkey dick cams you mentioned don’t do well in heavy *** trucks. Smaller cams actually work to our benefit by having an earlier IVC, you start making power/torque earlier.

If you chase a number, you’re going to be disappointed.
