Too much of a converter?

[bmoparmofo]

Hi, I have a chance to maybe get a deal on a flex plate converter setup. I just wonder if the stall speed will be too much for the car. Here is the link to the set up   http://www.jegs.com/i/Turbo-Action/912/17805STK/10002/-1     The car is a 69 Charger, 383, .030 over 10-1 comp, 495 lift-268 duration (I think thats the duration, I have to look it up.) 727 trans, shift kit. I havent picked a gear ratio for it yet. Was thinking a 3:91. THe car will mostly be on the street ( if it ever makes it out of the garage). Judging by jegs page it looks like the stall would be 3200-3400 range I think for my setup. Does it seem too aggressive for my setup? I was looking at turbo actions 11" hemi converter as well, they also have another 11" converter for about 120.00 less that says not reccomended for hemi or 440-6 pack. The hemi converter is 428.00 and the other 11" is 309.00 Any thoughts on if its too much stall for the car? Also the one with the link (Jegs) is a 10" converter. I really dont know how big of a difference or what the deal is between the 10" and the 11" Any help is appreciated. Thanks gang!

for a street driven car that is a hair high, but will be VERY snappy off the line.  i had a 10 inch 3000 stall in my car when it was an auto and that was a pretty good all around converter. in my opinion the key will be your cruise rpm for a daily driver type of car. you dont want to be doing all of your cruising while "slipping the converter". this will create lots of excess heat in the tranny and can lead to premature failure.

My opinion on street-driven converters is that once you have enough stall speed to spin the tires, anything more is wasted.
What's the difference if you break the tires loose at 2500 or 3500?

The feeling of driving around half in neutral that a high-stall converter gives ruins a car for me.
If you have slicks and want best strip times, you need to maximize launch and match the converter to your purpose. If you have an engine that won't pull until 3000rpm, you have to have a loose enough converter to drive it. If your purpose is 99% cruising Johnny Rocket's and your motor's not radical, it's more pleasant to have a converter that doesn't need 1500 rpm just to roll off a stop sign.

The super street 11in for $309 is fine for a 383 street type build which doesn't make as much torque as a 440. If you're thinking that you might build a bigger motor with more power at some point in the future the "hemi" converter would be worthwhile purchasing. 

The 10in unit is something that you would use on a more serious street/strip build.
