I think you can get into the high 11's NA, and spray 150 and run 10.7's. You could work it down from there with weight reduction and small changes.

not sure what the DA was that night, we're about 700 feet above sea level I think.

i know the car was running rich that night, you could smell it.

So the question remains, make the move to auto? whose done it?

I might end up saving my motor that way, correct?

You can use devices such as a window switch to "save" your motor if you happen to miss a shift, or break something. But an Auto will make it nice to be spraying though shifts.

I think you should be able to get more out of the combo.....

My car chassis wise
8pt cage
9" with 4.56
Lower Control Arms
Panhard
Long TqArm
QA1's 0,0 - 6,6 Stock Springs
Vipered T56 With SFI Bellhousing
Spec 3+
Tick Hydraulics
Strange DS
Billet Specialties Wheels with MT Fronts and 28x10.5 ET Drags (tubed)

Motor Last Year
Stock Bottom End
LS6 Intake
Patriot Heads
Thunder 224 Cam
Hooker Super Comp Headers

Consistent 11.60's at 3600-3700 Lbs Race Weight(full stock interior)

This year I rebuilt the bottom end to a forged 383 stroker and have a cam that specs
close to the T-Rex V2. I also swapped the carped and ditched the heat and ac, and
put kirkeys in it to get to 3250-3260 Lbs Race Weight.

10.89 - 10.90's

This year and last year I left off the 2-Step set at 6200-6500 and shift at 6500-6800 RPM
and wouldn't say granny shifting but shifting like a middle aged woman ie not powershifting.

Question is, what do YOU really want? There is tons more left in your combo on the T56. If you're worried about the motor when you miss a shift run a window switch.

You might want to measure the angle of your lca's. My car came around huge going to the middle hole. I don't use up the whole track anymore... although it's borderline boring now.

5500ft DA, 10.02 @ 136mph, 1.39 60ft.... and it's not even close to being optimized yet. About 650 rwhp NA. 3400# raceweight.

Well I did more thinking last night. I do love throwing gears, seems more fun. But i've never gone down in an automatic with any sorts of power. This year I bought a 730rwhp C6, and it just blows my TA out of the water...so I have that to row gears in...so I'm thinking go with the auto swap with a trans brake.

I might find racing even more fun if I'm getting consistent. We'll see.

Please keep the replies coming, I appreciate the posts!

$3k is alot of money if your just looking to shave off some time. Really, what are your plans for the car? Are you looking to bracket race, class race or just max out your combo as a street car?

IMHO a weekly bracket car would be better served by an auto. Otherwise stay with the stick and have fun working out your combo. It will be more exciting than the automatic when its figured out.

For myself, I am thinking serious about a weekly bracket race at my local track and plan on building the car accordingly. If I want to take home some of the prize money, a deadly consistant automatic car is in my future.

The car is drag only at this point. And slowly will become a faster drag only. Only time it will see the street is when I drive it a mile down the road to the track and back.

I'd like to get good, and win a few bucks, so that's my goal...after all of the thinking the past few days.

Just to show you the difference between a 6 speed and an auto in the same car.

I ran 12.32 @ 114 with a 1.88 60ft at -1400DA with the 6 speed.

I have gone 12.08 @ 112 with a 1.63 60ft at 2700DA with the 4l60E and a SS4000 converter.

I should have a chance to run the 1/4mi in much better air in a couple weeks. I don't see why the car shouldn't run low 11.90s in better air.

So the car picked up 3-4 tenths and it is a hell of a lot more consistent than the 6 speed.

I think if you plan to run 10.00 and quicker the TH400 is more reliable.

I agree.


I'm getting ahead of myself, but what kind of convertor should I be looking for?

I was leaving off my 5 step at 5500 rpm, 3:90 gears

With the spray, I'd like to dial in around 550rwhp, and whatever the torque turns out to be.

10.5 - 11.0 I think you could hit haha.

I had the white Camaro running 10.9@122/123 and 10.00@133mph on a 150 shot, 28's, 4.10's, 8" 4800 converter, @ 3300 race weight.

I think running 10.00 is pretty cool, car is still streetable and a lot of fun. I'd try to get the car down to 11.2's or quicker so that you don't have to spray a big shot but that's just me.
