Well I thought now is a good time to put this up. I grabbed 1 of PPP's 426 short blocks to go with the mods I already have. I'll add more info as it comes but as of now, in addition to the SB, I have 44lb injectors, new push rods, lifters and a custom, somewhat more aggresive cam going in this week. My previous best on a mustang awd dyno was 381HP 386TQ. Also PB time at atco, nj was 12.4@109 with a 1.78 60ft.

Nice! I'll subscribe to this... keep us posted on your results. Adding the 426 to your existing mods will result in one BADASS Jeep.

Everything, including tune is getting done at Tune Time in Toms River, NJ. They talked me into doing a set of AR headers now instead of later. Figure may as well, since no labor charge and all. And its only money.

Well picked up the old girl a few days ago with the soft "break in" tune. Can say the power increase was immediately noticeable even though I have to be easy with her. Took a few miles(80) to get the computer to adjust to the cam and start idling without stalling. I have it down to 800rpm now and it definately sounds nasty. I'm leaving here for now, but may drop to 750 when I get the re-tune in a few days. More info to come

I am about 30 minutes from Toms River and never heard of Tune Time. I am interested to see what they can do with your truck.
