Not sure if this is good, 383 LS1 11.347 It's a 383 LS1 (alot more mods, but these are the major ones)
eagle rotating assy 3.905" bore, 4" stroke 10.9:1
LS6 heads ported by Pro Flow
Harland Sharp 1.8 rockers
G5X3 cam
Victor JR/90 degree elbow (intakeelbows.com) Fast 90 mm tb
Kooks 1 7/8 headers, 3" duals with x pipe and moroso spiral core mufflers
T-56 from T56rebuilds.com
Mosier 12 bolt 4.56 gears
These runs were on pump gas n/a, and taking it kind of east on the transmission (have about 800 miles on the trans, I just didn't want to beat on it that much until I get serious and put the squeeze on it later in the year) ...this was letting off throttle completely between gears while shifting (quick, but not extremely fast), I was in 5th gear through the traps too... I figure it should've ran better, but I'm happy with it so far, the car put down 430rwhp and 421rwtq (seemed kind of low #'s) last year when I had it tuned at GMR Speed... I changed MAF and headers, I wanna get it tuned again but dont know anywhere else around NE Ohio, I'm willing to drive!
best run
60' 1.573
330 4.676
1/8 7.275
mph 95.32
1000 9.416
1/4 11.347
mph 120.18
closest run
60' 1.578
330 4.697
1/8 7.293
mph 97.62
1000 9.463
1/4 11.417
mph 122.03
It seems like the MPH is kind of high for the time... or is that normal? I'll post vid tomorrow

I'm boing to chime in and say that your ET and trap seem a bit low to me...I've seen a few local M6 guys run similar times with cam only 346s...Your 60's look very good for an M6...I'm sure other LS1 M6 guys will chime in...I thought that cam was fairly big...Its an LG cam right? What do they say? I just think that LS1 383s should spank 383 LT1s BUT we'd be a good race...

ehh... thats what i hope to be running with a heads/cam 346 ls1. your 122 trap speed is pretty healthy.. thats a 11.0 trap speed.
check your tune though, your should def be a 10 second car.
