Did manage to nail 1 1.8 60 foot and sailed to a 13.1 @ at nearly
105!
I had 235/40 18 BFG drag radials....
IMHO rockers and springs are not a major mod as they probably only added 15 hp or so... I gained 3 mph from them. However i do like the fact that i have good springs and i religiously spin the thing to 6500 and it keeps pulling and the 2nd gear bog is gone.
(So.. he had GTP air box, down pipe, springs and rockers with a shift kit and tuning, plus 1.5" shorter tires that were drag radials.)

And after doing a 01 LS6 cam ang going back to stock 1.7 rockers
He ran a 13.201@105.25mph with a 1.98 60ft.
This was with the 01' LS6 Cam, GTP intake with cone filter, head light out, catless DP, stock cat back, stock rockers, 918 springs. Shift points 6500 and my tune up, home ported intake neck and TB. 105! Keeping about 13.0 AFR and 28 degrees of timing. AIT temps were never below 95.

Yes, I was so close to those 12's with just bolt ons! I wish I would have had more time that year to at least get a few more runs in to get that high 12 with bolt ons.
