It has lived and died a few times. Having trouble keeping the trans alive. Here is a different throttle arrangement. This was either 1 LS2 and 1 LS3 or dual LS3 90s.

I'm not keen on running it in 4WD with the stock front drivetrain. It's also pretty hard to keep straight in 4WD. Haven't made it to the track this year. Waiting on a trans now and the track will be shut down for the season soon.

Ahh, that makes sense. Can't wait to see what that runs. From my experience (on a high powered vehicle), when you spin heavily and then complete your run, your mph will never be as high as if you hooked and made a clean pass. For example, I had a mustang that would run 11.0's at 128 mph. That was on a ET street. Just for giggles, I ran it one time on the stock pony wheels/street rubber. It went 12.10 at 122. I couldn't give it any reasonable throttle until it was in 2nd going into 3rd.

Since you already went 114.5, I bet your truck is going to fly when you get it to hook. Would think that mph will come up to around 120 maybe....just speculating. Either way it should haul the mail. Any idea what kind of power/performance it should put down?

I'm hoping it'll do similar to this: https://www.performancetrucks.net/fo...ex-cab-475282/

Haven't made it to the dyno yet either, but it move around 2000 CFM (140lb/min) airflow.
