Sounds about right to me. I'm sure Ron will chime in on what he uses.

how much do you drive it and how far? how often do you really race? that cam is perfect for street car i like a tight 10 inch for street car. if you really want to run a # and dont care about slipage/trans heat/gas mileage ect.. go 4k stall

im in the middle of putting all this together and i have this "race" converter here. i dont know what its going to do. i want to have a "racey" street/strip car and i figure the 557 is about the limit for the Cr i have. i guess if this stall is too loose i can have it sent somewhere for a tighten up

Try it, Should be close to "ideal" for a street/strip deal.

Its hard to say what that conv will stall at behind
that 440 but I would guess in the 4500 range... which
is still fine for the street

For the street..................
What's the difference if it starts boiling the hides at 3800 or 4500?

If it's an actual "race" converter, it'll likely slip so badly below the lock-up point that it'll drive like crap on the street. Try it and see if you can live with it.

IIRC, 383man runs a Dynamic 9.5", as do I. I have no idea if they're configured the same, though.

Re: whats the perfect converter for the 557 cam in a 440 - 01/19/11 04:58 AM

are the dynamic 9.5s all custom or is it a off the shelf converter?

I believe they always build to order...I run a dynamic 9.5 that I boughth used. It's actually too tight for my combo (built for a more powerful car).

what

we have used 5200 stall race converters on the street and they didn't drive like crap on the street. a converter doesn't stall untill power is applied.

I'll be running a 5000 stall in my Rampage as a
street conv
EDIT
I would call the company with the numbers from the
conv and ask what it will stall at behind his set up
that would be closer to being right than us guessing
at it

its a tci unit.. i called with all the numbers.. alls they could tell me is that it is a custom 9 inch race converter "probably too loose for the street". the man i bought it from is a dynamic customer, this was a "backup" converter he tried and he thought it was about 3800-4000. it was a racecar so we dont know about the drivability. im going to throw it in and see what happens!

I have a 8" thats going in my Rampage and I called
T/A and talked to Paul, gave him the numbers on
mine and he said its a 3800 series but after telling
him my engine and vehicle specs he figured about
5000-5200 so I'll put it in and give it a try... the
most I might have to do is pull it and send it out
to get adjusted... one thing I liked was he said that
conv is a very efficient conv with a low slippage
rate

I think it is worth trying. Let us know two things:
1) How it drives pulling away from the stop light (normal traffic/slow).
2) What the WOT stall turns out to be.

Different people will tolerate different feel during normal traffic driving. If it stalls around 3800 rpm in your combo, I think it will be fine.

i dont care for TCI.....everyone ive ever ran was inefficent. best vert would be an 8" from a reputable manufacturer.ATI,UCC,coan,TA for example.

Like Ron(383Man)and Brad(BlownBudget)I run a 9.5" Dynamic,behind my modified 440, that flashes to 4500rpm,and drives like a stock converter on the street! I've been using it for 5 yrs. now,and couldn't be happier!

I also run the Dynamic 9.5 street/strip converter behind my mild 440 in my 3700 lb 63 Sport Fury. It has 906 heads that I ported myself. I use a stock stroke 440 with the .557 MP cam and I love how it drives and races with the 9.5 Dynamic unit. Mine will flash about 4200 and has gotten me a best 60 ft of 1.57 with an 11.49 et and drives around like a stock converter. We also have the 9.5 Dynamic unit in my sons Dart that uses a .030 over 400 (406) with the .557 cam. He uses Eddy RPM heads and 3.91's with a best et of 11.45 and a best 60 of 1.60 as I use 4.30's in my 63. We both really like how well the converter works in our street/strip cars. Ron

I have a 440 with ootb eddy head and a 6 BBL.In a 3895# 70 roadrunner and 4.10 gears. It has a PTC 8in that stalls at 5000 rpm.Has gone 11.53@117 in street trim.

when i hear statments like "it flashes to 4XXX and drives like stock" THAT sells me on a product! ive had a 1k converter in a late model trans daily driver and it was the best thou i ever spent on that car. what a difference the right stall makes. im going to try this stall just so i dont always wonder "what if..." if it doesnt work im going dynamic!!! (are they pricey?)

Re: whats the perfect converter for the 557 cam in a 440 - 01/20/11 04:25 PM

not a big tci (TOTAL CRAP INSIDE)fan at all
but heay if it works ok,
I'll take a hit there,
but i run turbo action/ dynamic
prefer dynamic, much better tech help
but a good 9-9.5 convert should work great on
a street/strip car with no bad effect,
make sure tho you run a good trans cooler/lines

I'm sure you have enough experience to know that a converter can be configured a bazillion different ways and that has a direct impact on the way it responds to things like part-throttle application below the actual stall speed. Some units still provide a reasonable amount of fluid coupling under those conditions, while others are just "slip sliding away" (to borrow a line from an old Paul Simon song).

I won't claim mine drives like a stock converter under the stall speed, but it's a lot less "slushy" than the "brand name" 10", 3800-stall, unit it replaced. It also picked up about .2 and 2 MPH due to reduced slippage.
