If you ask me.. the stall on that converter is kind of high. 5400 for a big block car..

My current T/A 8 inch SS converter flashes to 5800 to 6000 RPM depending on the track elevation and weather, I shift it at or close to 7000 RPM and it drops back to 5800 to 6000 RPM according to the VDO Extreme playback tach. My old ten inch custom built converter flashed to 4400 RPM foot stalling and it would drop back more to around 4800 to 5200 RPM depending on the shift RPM, the 8 inch is .2 ET and 2 MPH faster than the ten inch was with no other changes I have a T/A 9 inch SS converter I will try next, test, test and test some more

i dont know jack sh%$ but the way i see your setup, it looks like an endless instant center. that is the same suspension pro stocks used in the 70s and it worked. i would lower the top bar a hole, maybe raise the spring eye a hole and work with what you have before spending the money on changing it. your car is not really that fast plus you have a huge tire on the back. i dont think ladders would pick you up that much

Well I read the original post this AM and I was thinking the exact same thing!...EVERYTHING Sixpac said. You have some decent pieces in that motor and at 3000lbs with driver SOMETHING ELSE is wrong. If everything looks safe under the car e.g.- weld integrity etc...I would only put a good pair of shocks on it. Maybe D.A. Strange without the coilovers or even the adj Rancheros. That MPH reflects about flywheel 525 HP. I'd suggest some of the more frequent oversites;
1)Hoodscoop and/or sealing problem
2)Carb improperly adjusted
3)What sparkplugs and gap AND wires? AND ignition?
You'd be surprised how much ET/MPH you can loose from those 3 alone.

I'm looking at trying moving the bars around to see if it helps don't know if you can tell by the pics but 1 arm is at a different angle than the other so more t n t is definatly in my plans

---

I would move both of your attachments down one hole Do you know the intersecting points(instant center maybe) of the current set up? If not look up how to compute the instant center of your set up and calculate it BTW, I seem to remember the reason the old Pro racers got away from the ladder link rear suspension was that they where breaking the main leaf at the front spring eyes Not good Is your leaf spring mounts to the rear end housing a floater? It doesn't look like it is the reason I'm asking, I'm not even sure if it should be or not

No does not look like it

My Duster has a leaf-link in it, but it differs a bit from what you have there. My upper housing bracket has 2 holes and the front is a modified stock framerail. The car doesn't have near the tire you do and 60'd in the 1.36-1.38 range at Norwalk, 1.40 everywhere else with a tired ole motor at 3150#.

As mentioned, I would address some other things before changing the suspension.

Good Luck
