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

 

lol it can become a disease.

 

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
