My Blacked out 383 LS1 '07 Tahoe Autocrossing pics/vid
Here is some awesome pics and a gopro vid from last sundays autocross event in Great Falls Montana where im stationed at. I had a blast running the truck while my car was down and i surprised quiet a few people with it! Let me know what you think.

Its a 2/3 drop. Bilsteins shocks, 22x10 OZ rims with a 305/45 Toyo ST tire. Otherwise stock with the exception of energy bushings and 373 gears.
Motor is a forged 8:5:1 compression 383 LS1 with stock ported heads, and a small 218-220 .525 lift 114 LSA baby boost cam. I had an STS kit but took it off a month ago for repairs. Trans is a few days old levelten built 4L60E. I did the tuning via HP Tuners. Ow yea 1 7/8 Long tubes, through a dumped 40 series flowmaster dual exit out. Its not the faster N/A. But better than stock.
Looks like fun. I'd like to try it with my 05 ecsb turbo Silverado. The way I figure, I'd hit full boost in the straights just in time to let off the gas then I would understeer over every cone on the course. lol
Nice man, its good to see other guys that are wanting to autocross the truck... I am currently putting Atomic's coil-overs on the front and going to do a 4 link in the rear of my Silverado.. I miss auto-crossing, and even though I have a C6 I still want to autocross the truck.. We'll see hoping to get it together before next season!
