Went to the track tonight and the best it ran was a 8.80. I doesn't feel like its pulling like it should be. any suggestions what could be wrong? it ran a 8.8 with just a converter, headers, and bumping the shift points up. now after the cam it doesn't feel any better. From a roll i can feel its a little stronger but cant go from a roll at the track. i dont see any reason why this shouldn't at least be running some 8.50s. It ran 9.6s completely stock. if i cant pick up one second with what i have now im choosing another hobby.

Your tune might not be god fo your cam, your cam might be too big, the heat didn't help you for sure. Did you have any traction issues? There are a million reasons why you didn't gain anything some of them are in your hands, others are not controlled by you.

Take a deep breath, relax and go again in a week or two and see what happens.

You've gotta be patient in this hobby too good results will come it will just take you being patient. Good weather. And when you go record every variable possible from run to run and from one weekend to the next. Take all this into consideration and you'll see improvement even if the timeslips don't really show it. If you go from 9.0s in cold weather to 8.9-8 spinning in the 100deg heat then IMO you've picked up a he'll of a lot.... Think about it

I think you need a bigger converter

i swapped to 4:10s and a tru-trac and went 13.0 @ 104.2 the heat is murdering me plus my converter isn't big enough. keep in mind, this is my DD/Family ride. i havent taken anything off of the truck, it still has the tow ball on the truck and i run 3/4 tank of gas or a little less. in the heat your truck is pulling timing i bet. mine pulls it like crazy.

it use to foot brake to 3k. but after the cam swap it will only go to about 2600. what converter would you recommend? size and brand?

1.88 60ft was the best last night. thats about what its always done

Circle D 3200 (reworked 278mm) tell Chris to make it as loose as he can bc mine flashes 3400ish behind a 500 flywheel hp motor

I do agree the cam might be a little big for such a heavy truck and little converter but still thought it would do something.
