For starts I’d like to say from what I’ve read through this community everyone seems extremely helpful. I’ve had my 6.0 2500hd for a little over a month now and I love it! I’d like to cam it for some more pulling power. From what I’ve found In my research gpi and tsp make vvt cams. What all supporting mods such as springs, rods, need to be done as well to make it as reliable as possible. It has 130k on it. Also once it is cammed will it be safe to drive it to my tuner. Thank you for any information you can provide me with.

 

The valve springs and supporting mods totally depends on what camshaft you pick. The smaller the camshaft the less you need to do. But any camshaft will require the correct length push rods and should have new valve springs just for good measure.

If pulling power is what you want you need to stay with a small camshaft because anything large will require an aftermarket stall torque converter and that will not help you any. Most of the "stage 1 or 2" camshafts work with the stock torque converter.

I wouldn't even install headers either, just do a camshaft upgrade and get a tune done. That will pick up some decent power on 89+ octane fuel. A small camshaft "should" run okay on a stock tune so long as you don't delete the VVT.

 

Yeah I want to keep the vvt for the benefits it adds I think a stage 2 would be the most beneficial. If I’m not mistaken a phase limiter needs to be installed as well correct? Yeah I will be keeping the stock manifolds. Thanks for the response.

 

Did a TSP VVT cam in a buddys 6.2 and it ran very good on 87 octane and was very easy to tune.
It had a stock 4L80E torque converter and idled like stock.
I cant find the cam on their website now tho.
