60' footing under 1.40
Anyone 60' footing under 1.40? What's your combo? Are you using the HR bar, Wolfe bar, coil overs, four link, tire size?

My best 60 foot was 1.47, I have South side machine bar lowers, Edlebrock adjustable uppers and an HR bar with 28 M/T's slicks on a 10 inch rim. I am pretty sure my pinion angle is at -3.5 degrees from what I can remember. As far as the rear goes, 3.42's with 33 spline axles,and spool.

My best is a 1.51. I think my problem was that I ran M/T 28x10.5's on a 10" rim, and I needed 15 psi in both air bags to insure the tires would not hit the fender lip. This totaly took suspension movement out of the equation. I have installed QA1's all around, fully adjustable lowers/uppers from Wolfe, -3 pinion angle, 3.42 w/ a US/Strange carrier, T/A Perf. cover, and Moser axles w/ Mark Williams C-clip elim.

not sub 1.4 but 1.41's
t-brake launches at 10psi (electronic boost controller) stock springs stock uppers stock lower (bottoms boxed) stock bushings MT drag radials (#23psi) and HR parts sway bar the trans, driveshaft and rear are built for low 60s 2004r , 9"art carr 14930, chromoly shaft , spicer yokes and ujoints moser 33 spline , moser spool , c-clip elems i probably could cut 1.3xs by dialing boost up a little and toss on some slicks , but with just a stock bottom end i cant be too hard on it. i run a stageright t-brake which engages by placing trans in 1st gear and releases by bumping out of 1st , because of this the shifter is in 2nd when you leave the line and 1-2 shift is auto trans controlled occurring early (5150) and within the first 60' (actually 42') , if i could carry 1st gear to 5850 the 60 should drop ...working on that as we speak
