No I dynoed on 265 75r 16 bfg all terrains

 

I bet your numbers would be a lot better with a street tire pattern in a normal size along with a better intake. That motor has a lot of air flow potential but the truck intake is choking it Im sure. A better flowing intake will help carry the hp numbers on up higher. Can you post the dyno graph? Also I wouldnt get too stuck on the dyno numbers, take it to the track and see. A couple years ago a guy with a built 5.7 and radix in a cc 4wd truck only dynoed like 450 to the wheels but clicked off mid 12 second passes on 22s which obviously dont add up.

 

thanks LOL I guess il take it as I just need to spend more money. Haha

 

397 to the wheels is nothing to sneeze at though. I was thinking a little higher as well but you never know, no 2 dynos read the same plus summer time heat, etc.

Looking at your mods, the only differences in our motor setups is that I'm running a cam with more duration on a 111 lsa and I have FAST 90/90. Your CR is a full point higher than mine though. Who knows....

 

What converter are you running?

 

I'm using a stock gm converter that was refreshed to stall

 

Ya, can you post the chart??????????

im trying to decide what cam to put in my 6.0 but i want to see what it lost down low, about 2000 RPM, did you start that low???

I Started my pull at about 1700 so that i could compare for towing...

 

My. Pull was at 3000 because of my stall but I'm sure it made good power down low that's where it is suppsed to shine I can't post it on here but I can send you a pic of it if you send me your email

 

Thanks! ya, my dyno guy just locked my converter in third...
