Thanks Spoolin.... Well **** someone send me send me some slicks so I can test out this transbrake... Chris at Circle D said it should stall up to 4k on the brake. as for the dyno, I'd bet i'm currently every bit of 4550 or more trapping 98mph. It's the same tune as the 617 dyno with the 5 speed. I'd guest the auto is eatting a good 50-75HP.

Llaverito your truck moves man, no doubt. You got a slip you can post up? I only ask because it seems your currently the top 4.8L record holder.

00Z71, about the timing, I'm running 16.5 thru peak TQ, then ramping up slightly thru 6.3

I'm just amazed what the stock motors can take these days. I can't wait to turn up the boost on mine some more, turbo is just itching to work a little harder

Awesome times, especially on those wheels.
