Interesting.... Motorweek did an episode with two stock Corvettes (one auto and one manual 4+3)back in 85, and the auto was quicker. YouTube link is below. Great episode....

Two reasons ^There^.
1. Motorweek (and ALL car testing publications (outside of Fast Fords & Muscle Mustangs) don't know how to drive sticks, and drive like pussies. That puts the stick at a disadvantage b/c in a 230hp car all you need to do in an auto car is push a pedal all the way to the floor, to get the best time (or damn close to it).
2. The early C4 sticks, the 4+3, is a rough, clunky shifter. Harder to shift it FAST.

But mostly it's the driver(s).

Stock for Stock. Manual all day. Find a automatic LT1 that runs consistent 13.5's and 13.4's and the occasional dip into the 13.3's. I'll wait...

^Yep. Hell, find one that runs a 13.anything! Some probably exist, but I ain't seen it at the track.

I just watched an episode of Roadkill; Finnegan got a C2 with an LS1 and he met Dulcich at a drag track in SoCal to race. Dulcich brought a '00ish C5 Auto Vert. Dulcich ran a 13.5/105. I'VE ran at 13.5/105....in Vegas (2200' elevation), with an engine rated at 50 less hp!

Stick FTW

There are so many factors to that equation!!! All the drag racers I know all run Auto’s , it’s just constancy. The big boys all have high dollar autos . Stock year model vs yr model c4’s though ultimately comes down to two things in my humble opinion. #1 is rear gearing . Close #2 , if not actually #1 is driver . It certainly take more skill for a stick car to get down the 1320 ft then it does a pcm driven 4l60e car . A good stick guy would touch the clutch once at the tree and power shift every gear ( the stick cars are almost always a steeper rear gear also ) !
I personally have an Auto car but it is looooooong since been close to stock . I’m making over 500 both horse and torque ( Golen 396 stroker .) which disintegrated my slightly built 4l60e on the first real rip for my tuner . 3/4 clutch gone at 122mph . I have now invested in Allen and Franks Race 2 4l6Oe from Performabuilt. Very nice 700 rwhp Dyno checked unit . We will see here in a few weeks how we do at pacific raceways up here in Seattle . I will post a N/A slip and a 200 Shot slip . If I make it to a second run without a cage ???? I still believe I need gears in my fresh Dana 44 swap . But I am Gonna run what I brung this summer ( do the 3.73 swap for a winter project ) oh 3.07’s is what came in the 44 . So that also will be fun 🤩 for some 3.07 numbers . I appreciate everyone of my C4 forum Brothers and ummm ( sisters ) thanks for all the great knowledge and Amazing part purchases !
GOD bless ,

Ditto with my '87
I could never 60ft as consistent with the stick as after I did the auto swap .
