Too many differing opinions.

Cool idea.
I'll start.
94 Z28
bone stock shortblock from an unknown mileage Caprice (it looked pretty good)
new bearings, clevite
XFI 468 cam 242/248 .584/.579 on a 114
TFS heads lightly touched up by Oddy's probably flow 5cfm over stock TFS
30lb Accel injectors
Pacesetter long tubes
Magnaflow cat back
TFS pushrods
Comp roller tip rockers
918 Beehives
Custom tune by Paul at PM Performance
th350 manual vb
Art Carr 5000 stall
Strange Dana60 3.73
Lots of suspension goodies
some weight reduction (still have a way to go) prob 3300 with me in it

Best E.T.

60 ft 1.6462
330ft 4.8792
594ft 7.1202
1/8th 7.6144@ 91.77
this was at an admittedly slower track (it is sort of uphill, lol) and i rode the brakes just a touch at the end (was bracket racing), I broke out anyways
It would probably run a 7.45ish/11.60ish at any level 1/4mile track. I will be at the track again this sat with a lot of new goodies, and hopefully a video/sound clip by Monday.

For comparison.
96 Caprice
45K mile Caprice shortblock, untouched bearings just a steel oil pump driveshaft and white spring
AI custom cam, Mid 220s intake under .570 lift both sides with 1.6 rockers
AI 190cc ported LT1 aluminum heads
32lbs. LS1 injectors run at proper 58psi(got them cheap would not do it again)
Clear Image Automotive "Budget" midlength headers 1 5/8" tube 3" collector
2.5" X-pipe dynomax Ultraflos and resonators
1.6 ProMagnums
918 Beehives
Mailorder Jeff Creech tune
ProBuilt Automatics 4L60E three years old at time of run
ProEdge 3400 stall lockup converter
8.5" 10 bolt Eaton posi and Motive 3.73s
26x10.50 Hoosier QTPs, street tires on front
58mm TB
mechanical WP
belt off
BMR LCA, Airlift bags, stiff handling shocks all round with stock springs
Approximately 4150lbs

1.639 60ft
4.861 330ft.
7.591 at 90.15 1/8mile
11.953 at 113.07 1/4mile
There was about 8-9K miles on the topend at that point. I did uncork the exhaust and pull a little extra weight to get the 11.9, but that was because I made a couple 12.0 passes through the full exhaust at about 4200lbs, when you are that close you would jump through a couple hoops to make the 11 happen too.

That was last fall at Great Lakes Dragaway which is 150 miles from my door and the first day I was told the front tire was getting air.
The other end of the spectrum was 12.8 at 105.6 with this car in 105F degree heat in June at Gateway International with big street rubber in front(58lbs each), swaybars hooked up, just drive it 500 miles bolt on the slicks and run, DA was said to be 4000ft. by the bracket guys with weather stations. Definetely worst case senario at least for the midwest.
Normal performance for the car falls in between those times depending on weather and preparation.
Power seats, AC, ABS all there. This is a true daily driver spring through fall, I wont park it till mid november or so, it is NOT a good car for snowey travel, other than that it is great.
First day the wife went down the strip she came within hundredths of my ET, the car is just point and shoot.
