This would be why I have so many sets of injectors.

I'm looking forward to see which cam you choose and to hear about the results!

Not sure how relevant this will be, but since you brought up towing, I will add in my own anecdote here. I have a 6.0 with PRC Stage 2.5 LS6 heads and a Texas Speed stage 4 high lift truck cam in my 2004 1500 (stock truck intake). My truck has a 9" lift with 36" tires, 4.10 gears, and a 2800 stall Circle D converter. I have a boat that I pull regularly an hour each way to and from the lake. The boat weighs almost 7k and the truck and boat together is over 12,500lbs. I have been pretty happy with how well the truck has been pulling the boat this year even though I really should have more gear than the 4.10s for the 36" tire and the 4l80. I don't feel like I went with too big of a cam (although someone who knows much more about cams than I do can chime in and disagree if I'm off base here) and right now my truck shifts around 6200rpm pulling hard all the way. If my truck was stock height with a 32-33" tire, it would tow better yet. I can't imagine wanting any smaller of a cam unless I was pulling something that is more that the tow rating of my truck.

Hopefully that helps in your decision making!

Thanks for the info! I am ordering parts this week and hopefully machine work will start on the engine over the next few weeks. Im not swapping the engine for a few more months(waiting for cooler weather). I decided on this cam https://www.summitracing.com/parts/sum-8720r1 as its just a little bigger than whats in my 5.3 but im hoping the additional lift with cnc ported heads and higher compression will net even better results/gains.

Thats pretty close to what I am running in my 6.0 L76. Mine is 228/230 so a little more duration, but only .585 lift. Same LSA. It's at the exhaust shop now for full stainless true duals with an X pipe, then off to the tuner to get tuned in.

Have you run it at all? I will be curious how your set up does on the dyno. If i could get a solid 350hp and maybe 400tq to the wheels i would be plenty happy. Its a heavy 4wd with heavy bfg AT’s on it so my driveline is eating up a lot if power. Keep me posted on how yours does.

I haven't dyno'd it yet, but it ran long enough to trailer it and get off the trailer to the exhaust shop. Then off to the tuner. My numbers will be a little inflated though, it has a blower on it.

Yeah your numbers wont apply to my build at all since you have a blower lol
