15.3@93mph with Futra GLS Tires aka no traction,leaned out fuel,and running on 7 cylinders. But the fuel pressure is going to be boosted when I get home again, new Komho 245/45/WR16's will be on with 16x8 black GTA rims and well, the head gasket will get fixed later.

I have only ran a best of 15.24 @ 90.8 this summer.

P.S. A few other mods I have, not listed in my sig, are: 1.6 roller tip rockers and A cut-out directly after the Y in the Y pipe.

No F-body here, but I've got a TBI 305 in my 91 Caprice. I got a 16.59 @ 82mph in it last year. It was my only time at the track. Mods include opened up air intake, free-flow exhaust, and hubcap delete that's about it. I also had bald, mis-matched, $15 used 215/65 r15 tires on the rear and 215/75 r15 tires on the front. It still has 2.56 gears and an open differential. I estimate the weight to be right at 4000lbs.

I just ran a 15.85 with crappy @ss tires and a heavy car, not to mention 'just an ok' launch. If I would have had two more runs and no front sway bar I think it would have been a good 15.5 or .6.
