383 Sonoma goes 10.46. Finally finished the LS swap on the truck, and took it to the track. First night out with it, it went a best of 10.50 with no tuning. On Friday night it went a best of 10.46@126.99 and then on the next pass lost second gear in the trans. It did have a 1.42 60' off the foot brake. I have not had a chance to adjust the Caltracs yet, so we can't leave off the brake. With some tuning I think it will go 10.20's, and then we spray it!!!!!! The combo is a 383 with Dart 225's, Victor Jr, 950HP carb, 234,238 .598,.605 cam, 4400 conv. with a TH350, 8.5" rear, and Caltracs.
Good Luck

I'm putting together an 82 S10 standard cab short bed. I have an LS1 full ported heads, valve job decked .030. I had to fly cut the piston's to clear the valves with the T-Rex cam. Carb'd intake set up with a 850 holley, 3800 stall TH-400 built and a 9in. with 5.00gears and a spool 28in. tall tires weld pro stars. I have done about everything to lighten it up and still keep it legal on the street. Oh spraying it with a 200hp shot with a stand alone system on 116. I hope it runs in the 10's or better I will probably have to change the gears to run the 1/4 tho.

Onequikss, did you lay down that 1.42 60' with leaf springs and caltracs only? What tires were you on? If so, that is the most ridiculous launch I have ever heard of.
Really nice truck too.

The suspension on the truck is 3" belltech dropped leafs with a 1" block, caltracs, rancho9000 shocks and lakewood 90/10's in the front. The tires are 275/60/15 Hoosier drag radials. I have some more chassis tuning to do to it before it will leave on the brake, but I think it will go 1.35-1.37 60's.
Thanks to all for the comments.

They work a lot better than people think. The last combo in the truck had a conventional small block with a 150 shot and went 1.48 with homemade traction bars.
