I have a 74 Duster with a 360, A500, 4.30 gear. I run 275-60-15 drag radials. Approximately 3500 lb car, maybe more, I will weigh it in the spring. My car is primarily a street car and highway cruiser, but i want to make it as quick as it can be for what it is.

My best time to date is a 13.36 @ 104.24 with a 2.08 60' time. I got in touch with a torque converter guy from TCS Performance Transmission in Burnaby BC Canada. It's a well respected shop here locally. His recommended converter should stall between 3200 and 3500. My question is, what could I expect for a 60' and ET improvement if I do say get a full 3500 stall from this converter? I know this won't be exact as there are way to many variables, but I'd appreciate opinions by the experienced racers here.

Thanks,
Cley

What is the current converter? Current 60 ft is soft for the ET/MPH. It will be quicker with a better converter - IF you can hook it up.
 
I plan on shock upgrades and better tires to adress that part of it. Plan is for QA1 Double Adjustable Shocks on all 4 corners to go with my super stock springs and 6 cylinder torsion bars. Tires will likely be Hoosier Drag Radials.

Why is the 60' so slow with 4.30 gears?
Does it spin at the hit?

You better weigh the car before ordering a converter.

The converter is here. It spun just a bit on the run shown. The converter was a super tight stock unit.

you gained 22 mph the last 1/8, that's good for the area of ET you are at. A sign the 5.9 is making good once it's going.
 
Is that a Bracket master? If so what did it cost?

15.00 60 foot. MPH has a mid 12ish in it.

Good looking side shot of the car!
