I’m not a W9 guy but your converter stall needs raised bigtime, and I mean bigtime

I talked to Paul at turbo Action yesterday and he suggested rebuilding the converter with 5500-5700 stall. ATI wanted to build one similar to what we have 3000 launch 5000 stall Still not high enough for a W9 combo. Edelbrock heads like mine A 5800 is ok.

It seems to me that the car is very under geared. The motor isn’t getting into its power range to move the car. The most important thing you could do now is take the motor out and dyno it. Then you will know what converter and rear end ratio you need without guessing. When you get that right you will see drastic improvement.
That would be my recommended course of action as well. Beautiful car, by the way.

I agree with others, you need more stall, I think it needs more carb too. Did you dyno the engine? Have you tried less timing? My Indy headed 434 made the most power at 34°, any more and power fell off. I'd talk to your head guy about converting the intake to a dominator flange.
IMHO your 60' and 1/8 mile et and mph are down too. My street/strip Dart has been 6.25 @ 110 and 10.008 @ 134.75 on pump 93 at 3293#, foot braking at 2000 rpms. it went 6.33 @ 109 in street trim last fall. The engine is 4.125" stroke and 4.09" bore R1, 11.2-1, 266/271° @ .050", .711/.719" at the retainers, ported Indy 360-1's and ported Indy intake, a 1050ish Thumper built 4150, 1 7/8" Hedmans. 727, Coan 8" that flashes 5600, Strange S-60 with 4.10 gears, Cal-Tracs, monos and Viking D/A all around. It's currently on a 275 radial, but previously was on a 325 radial. The engine made peak power at 6750 on an engine and chassis dyno, I shift it 68-6900 rpms.
I think my car will run well into the 9.90's in decent conditions. With some tuning you should run a couple tenths faster than mine. Keep after it, you'll get there. Great looking Dart too.
