If those are your only mods, you're looking at high 12s. You need a stall to run good times in an auto.

Look in the 3600-4k range.

Cam only my car has gone 12.80s @ 110.67. This is a garbage time but its a six speed with a grippy clutch and 245 nittos that won't really hook too well. That 12.8 run was with a 2.1 sixty haha.

12.9 N/A
11.5 N20

all at 7500+ DA

Would be high 11's on motor at sea level no problem.

A good cam only setup can do well, but the heads do need some help on these things.

I just went 12.0x@111 or 112 a couple weekends ago, can't remember the trap.

Set up: Stock bottom end 355, COMP XFI 466 cam (280XFI HR13), FLT Level 4 4L60E, Yank SS3600, Moser 9" w/3.70 and locker, Jet Hot long tubes, true duals. Basically full bolt ons, heavy stock Firebird wheels with ET Street slicks in back, full weight (except back seat and a/c). Got a few suspension mods but stock torque arm

I went 12.44@111 on a 1.75 short time with mine about 10 years ago at MIR. HOT cam, SLP shorties, stock cats, 4.10 gears, and 275/40/17 Nitto DRs plus the normal mods.

Don't know if it will still run it or not but still should be close.
