it has / or had something to do with Dynamic.

The Dynamic guy moved on? Or he took tct to dynamic? im not sure

not sure on the whole story--

What's it run in the 1/8? If I were doing one thing it would be a good port job, then get a converter next year. I've had good luck with Edge Racing Converters, talk to Andre.

Im not sure bout weight. But I got a Glass hood with and alum radiator. I also removed power steering to save some weight. Im thinking bout 3500ish maybe. Thanks for all the responses. The compr is 10.8 and the stall is a 10". My 1/8 is 7.32 @ 90mph (i think) not positive, im not at home and time slip is there. My fuel line is 3/8

you can try this I know other converter companise do this. let them know you purchased the converter thru them and its to tight, have them loosen it up a bunch thell them the specs get a price and weigh the cost of a new verse getting this one worked. then you may have enough left over to put some money into the heads or a gear swap. I suggest you run at least a 4.10 to 4.30. look on here for the parts most of the guys on here are truely honest about what they are selling. and if you need to ask about someone selling parts feel free. you will also find they guys on here are generally a very tight nit group. thats my

Finding out what it wants for a tuneup would be first in my book. If there is a very good chassis dyno and operater in the area, I would go there. Also, stuff like long collecters, cold air package, unstable timing, timing curve, cam installed centerline (maybe advance it?) and a bowl port and sharp valve job on the heads ( > $350? )to get the most out of it. If you have done the heads, great.
Try less lash, first on intake then exhaus. Watch the individual segments of the run, plus weather, to get accurate data.
Finally, the dyno will show if you need some jet changes, and if the air fuel ratio is right at all rpm ranges.

good luck asking a question like that cause you are going to get a thousand different answers. good luck on picking which one is right for you

I remember this well...I was chasing 10's along with Gary (UNLAWFL) in 2003...my big help was ATI 8" convert. and Cal Tracs with 4.10 I went from 1.58 60' to 1.45 best w/slicks. Call Cal tracs and get there 90/10 shocks ....and rancho 9way for rear ...my 2

Thanks for your guys. The 850 demon is out of box. Timing is at 36. 3" exhaust with flowmasters super 40's turned down at axle. I have wondered bout the springs though. Im using the Indy springs that came on the heads. (supp to be good for .600 lift). Im at about 6200 rpm when crossing the stripe. I do have a set of 4.56's that i got a good deal on. Thaught bout using them but man thats low for a street car. Plus I feel they will put the rpm's too high at the line. Not sure if stock bottom end can handle that kind of R's for long. I agree that i need a chassis dyno to see what works or doesnt. Just dont know of one around here.

Converter needs to go for sure.

I had a TCI 10 inch that at the time performed OK. But looking back it had about 13 percent slip, which sucks, plain and simple.

In my car a TA tight 8 inch that flashes right under 5k was worth at least .17 over a very decent PTC that flashed at 4200. Both converters calculate to 8 percent slip.

Id bet you would pick up .2 and 2 MPH with a better converter.

As others have said there should be more in your combo, maybe 10s as it sits. 10s with a converter change and tuning.

I didnt read the whole thread, but did you have the seats reground on your heads or are they the Indy supplied valve job?

I have to go with the converter here.I run a SB in my 3420# Aspen and i have a TCS 8" that flashes at 5400.Back in the summer my ET/60' times were all over the place and i was told the converter is on it's way out.I was also told TCS was no longer in business and bought a Ultimate 8",shortly after i found TCS again alive and kicking and sent my converter back and they replaced the sprag.I wanted to try the Ultimate before anything else from everything i've heard about them.The Ultimate was waaay too tight and slowed my 60' from 1.47-1.66 and the ET went from 11.0 -11.9 so 3 passes is all i made.Put my TCS back in and my 60' was back to a new best of 1.41 and ET best of 10.76.Oh and i run with stock leafs with 1 extra leaf each side and pinion snubber as well.I'd like to try Cal Tracs but don't think i'd see any improvements and no one makes 90/10's for F-body cars.
