Kris at Continental Converter is/has passed the business on but that's who I've used for many years and never sent one back for an adjustment............

He's sending a lot of stuff to Dice Performance Converters.... LANCASTER DOM !!!!!!

Just a guess on what will please you for driveability; it sounds like a stock configuration 10 3/4 Mopar converter, set up to act just like a factory original yet be built for the abuse a 540 can deliver is what will work well for you. I used exactly that converter behind a 535 cube wedge with a 590 cam in it, and it stalled plenty high yet was tight enough to not flash a lot higher at a light throttle application. If you take the K factor into consideration, it will give you an idea of what it will do in the car. Those converters were used behind 340s ,383s, and street hemis I believe. The stall behind a street hemi was about 2800 from what I have read, and 2400 behind a 340. That same converter stalled quite a bit higher behind my 535, like mid 3,000 or more.
A couple of things make me think this might be the right path for you. You want street drivability over ultimate performance for one. The other is street traction. A motor like that ought to be able to fry the tires at low speeds anyway, so a high stall loose converter just isn't needed much there.

GregI hope you are not inplying that this car is street driven as it hasn't seen the highway or city street in over 20 years, it is a dedicated bracket car, altho I would just love to take a blast thru the neighborhood just once and pizz off the neighbor's down the street.

I noticed this, think he meant to post in the Other vert thread, that's looking for a more street friendly vert.

While I haven't purchased too many converters for myself, I have helped many many people get their combos sorted out through the years.

I'd be surprised if out of all those combos there were more than 20 where the converter seemed close enough on the first shot where it got left in the car.
Most end up going back at least once. Several ended up going somewhere other than where they where made to get "fixed"...... Some just got replaced with something else.

I'm always amazed at how you can give the exact same info, and request the same stall to two different converter shops, and get back two completely different performing units, with huge differences in stall....... And sometimes neither is what you asked for.

Somewhere on this thread someone mentioned how many times a converter shop will try and give you what they think is what you should have, regardless of what you ask for...... Because they know better than you.

My feeling is......... Just give me what I ask for..... Even if it's wrong and will make the car slower. At least then I'll learn something.

my friend larry owned a torque converter rebuilding shop---he said most of the catalog converters are loose (inefficient)

Lenny's has been behind motors ranging from 446-512 in my Arrow and has been flawless. This is without a dyno sheet so I'm sure there might be more in it. He picked up 5 mph in the original Hughes the first time he touched it.

he is on my short list.

one day after submitting my tech sheet Lenny call's and we discuss my need's,, two weeks after I submit my tech sheet to TCI I still have no response,,,guess who is going to get my bussiness.
