I've never posted but this topic isn't a new one. I've got a 6.0 being bored .030 over. I'm wondering what would be a good cam choice for it, it'll be a daily driving truck. I want to be able to climb hills without downshifting. I'm running a 4.8 currently is why I say that but I have a comp cam xr265hr in it and perhaps this cam would be sufficient in my new 6.0. Also would the 6.0 bolt up to my torque converter in my 4l60E?

 

What heads and converter?

 

I have a set of 317's that came with the short block when I bought it and a set of 862's that I picked up last year. I plan on doing a little "work" to the heads, nothing fancy. The converter is stock.

 

I figured on using the 317's though

 

So not touching the heads and running 78 or 90 mm intake?

You don't even want to run a trailblazer converter?

 

I plan on buying a rotary tool and some bits to clean the heads and take some material here and there, only what I have seen on hot rod threads that the pro's do. I'm not going to go in there like Indiana jones with it because I'd like to not have to replace a head. As far as the torque converter goes I've heard of using a trail blazer converter once before but that's it. I'm on this forum to learn what I can do any advice/knowledge is appreciated!

 

If you don't know how to port I suggest leaving the heads be. Your current cam would work fine, it won't be anything crazy on topend but better than a stock cam.

 

I understand, I just want to make it "better". Ima die hard diy'er for sure! My truck is an 07 silverado classic. What year trailblazer torque converter would work? What would be the benefit of using one be? Remember I'm a newb

 

Thanks 03sierraslt. This is the link of porting the 317 heads

I was also looking for tips from guys who have done the 6.0 swap. I plan on doing this by the end of the 2017. I'll also be beefing up the 60E to handle the added power

 

I only ever recommend running a trailblazer stall to people who are set on running the stocker. The stock stall speed is so damn low, like 1900 rpm. You pick up so much more performance from a higher stall speed converter alone.

I wouldnt worry about porting the 317s. I'd put the 4.8 top end on the 370. Something in the 224 range at .050 duration cam. Pretty tame imo for a 370. But I'm not sure how much low end you're prepared to give up. There's the btr stage 1 cam. But I'm not sure exactly what you're after.
