Full weight 3600# with driver
TSP 231/237
Stock 853 heads

Previous N/A 12.40 @ 109 with a 1.80 - 60' - Vigilante 2800 converter
New N/A 12.18 @ 111 with a 1.70 - 60' - Circle D 4C 3800 converter

Time to put my ported heads on and run 11's N/A. Then the bottle goes back on...

good job man, i did 12.20@110 with my current setup. i have to work out a few bugs though once the trans is fixed and i should do much better..

Is the converter setup for nitrous? If not your 60fts seem slow for the mods you have done. You could already be in the 11's with a high 1.5 60ft.

Need to have your shift RPM set to shift in the 6,500 to 6,700rpm and watch it go!

Tis setup for the bottle as it will see a 250 shot after my ported heads go on. I barely footbraked it. I think with footbraking higher, it'll go low 1.6x 60' n/a.

I have it shifting between 6500-6600 rpms. The tune required very little changes to account for the higher stall speed.

seems down on power to me, or the trans is having issues. You should be trapping much higher and the 60' should be much faster.

Ther are bolt on only cars running that fast with that size of a stall. No cam needed. I think with a better 60 ft it will show more promise.

It's going to trap according to the power it makes. The car is a pig at 3600#. Seems on par when you add up the mods compared to the 13.6 @ 104 it ran stock.

Bolt on cars that are gutted running quicker than me.

Come on ladies, quit posting like know it alls. I've made 2 passes with the new converter and the engine has a hard 134k miles.

Well, you never said that. If that was said in the beginning you wouldn't have these posts. I would go through the motor with bearings and rings before I put heads on and spray it.

Just for your info though there are full weight bolton cars running quicker.

I'm not saying that I don't believe you, but I have yet to see (with my own eyes) a full weight (3600#) bolt on car run quicker than a 12.2x with stock gears in positive DA. I don't believe everything I read on the internet. FWIW, the DA on my run was in the 1200 range, decent air imo. An optimal converter for me n/a would be in the 4400 range, but I wouldn't be able to spray with that big of a converter. My car made 380 rwhp on a dynocom3000 n/a and 643 rwhp on a 250 shot with a safe tune (12* timing). I am not rebuilding this engine, it will be replaced with 400+ ci when it dies.

I ran 12.08 @ 112 in 2000' DA with 3.42 gears at 3500lbs. The car dynoed 330whp unlocked. It has also been 1.53 to the 60ft. There is a lot left in your combo even if you don't want to believe it.

I hear you, If I was in your shoes I would have a hard time believing it too and I would have to see one with my own eyes. My ws6 (almost the heaviest out of all f bodies) with a 3000 vig and longtubes, 3.23 gears and M/T et streets went 12.21. The car did that with my buddy driving and the car's weight was 3820 (250lb driver).

We are closer to sea level down here so 1200 da sucks here. So your times might just be on par. If you ran down here you would be in the 11's already.
Speaking of a 4400 converter, one of our fellow racers put that in a bolt on only car and has run a best of 11.89, stock gears and all. Still, it was a better da.

Yes there's some left in my combo. I am pretty sure that the heads (valves/valve seats) are showing more wear than the short block. We'll see what my results are when I get my hand ported heads installed.

I'm not a know it all by any means but that trap is low, period. If the motor is that hurt I wouldn't even think about spraying it. Also my car is 100 lbs heavier than yours and has trapped 114mph on its worst pass when it had a baby cam in it.

87silverbullet

Well either you had a shitty 60ft or you were spinning?

Could also be that your converter is efficient on the top end.

What was your 1/4 mile et?

I made a post to show the improvements from one converter to the other. This motor has always performed below average compared to other LS motors, a fact that I can live with. I don't consider the motor hurt, but could benefit from a rebuild. My future plans do not include the use of an LS1 block, so I will run the **** out of it until it's life is over.

I actually don't think the mileage is the issue...I'd bet it's that it's an auto, the DA wasn't so great...there's a lot of things there. My 2000 has 187K on it and traps 111 with stock heads/cam...but it's an M6, and I always get great DA on the east coast where everything acts like it's supercharged...I don't think there's anything wrong with yours, your setup just doesn't seem to be quite optimized for top end.

I agree with 87silverbullet. I have two cars stock internal that run 11.8@ 112-114. I live in Baton Rouge, La. and race @ NoProblem Raceway, both cars are full weight a 02z28 and a 00t/a and have more than 50 passes on them. I have extensive time on the dyno getting them tuned and that is where the performance gains are. I am not saying this is your case, but I have seen so many people spend big time money on parts and not want to spend the extra 550 plus to fine tune the combo.
