Wish I would of went with more converter mines a dog down low and the spinning doesnt help. I ran 14.8 @96 on 22's with a 2.4 60ft. I cannot hook at all. Ordering some slicks on friday hopefully to see what it really has in it.

im with nonnie. have you tried flashing that converter? I bet that truck would run good with a 9.5" 3600 converter. you can tow 2000lbs with it and a 40k cooler. hopefully its not alot of stop and go towing lol.

If your truck is any kind of a daily driver there is no way in hell i'd cruise around with 4.56 gears and 4k stall, that would annoy the **** out of anyone, Im not saying it can't be done, just saying you kind of lose the funcitionality of having a truck in the first place.

I say Leave the cam in there (Its a healthy size cam for a 4.8) and step up the stall/get LT's and you'll be more than happy with the results.

Good luck man

Oh no that 4.8 running 8.2s isn't mine but I do know it's not his daily track only mine still has the 3.42 gearing on mine, that one is my daily

I ran it Friday night with flashing the converter and the best I got out of it was 9.7 2.23 60' at 74 on 20 psi in stock 245/70/17 tires hooking up decent, my long tubes and 275/45/17 slicks are in my room just hanging out til I have time off work to put them on... An I thought about doing the 212/218 high lift cam since I already rev to 6800 rpm's ... Or would the low lift be better . I'm gonna keep the 3200 stall since I do have to tow

i would install the lt's and run it on the slicks before you make any decisions. view your timeslip after the new mods and decide from there

and how much weight do you tow?
