[quote=calrobb2000] hi ,
the dynamic worked good for 20 years and you want to know where to get a converter ? My Dynamic has worked very well so far. My friend's sucked. Nobody hits 100%, and converter tech & good builders can change over 20 years. If the new engine and the old converter aren't a good match, I'd like to know what other people's experiences have been. [/quote ]by your power numbers i would geuss your new combo will want a 7000 to 7200 shift and 6200 stall. As low as 5200 may work well. I would run what you have. I didn't see a lot of change fron 5500 to 6000 stall on my deal. So the problem becomes; if you mess with it you may go backwards. Test the car with the old one and if you want to know if a change is needed buy a new one to compare.

ATI here......Getting one for a big engine like mine wasn't easy....Love it. ATI is in Maryland about 60 miles from me, but I've never done any business with them. Dynamic is in Delaware about 120 miles from me. If there are other "close" converter companies, I don't know of them. And until what I have now is tested again, this is all "for informational purposes only."

I am using a 9.5" PTC that they built for my combination and street / strip . I have no complaints . But, It would be interesting to try a higher stall . Call PTC and see what they can do. I sent my 9.5" back to them after 13 years of running it, $150 + shipping to polish the hub and a refresh.

I used an A & A 10 inch medium stall behind my 408 Dart motor. 517 tq at 4600 and it stalled 4,000. There are three stall versions, about 400 rpm apart. Mine was the middle one. It had decent lockup. 2600 rpm at 60mph with 27. Inch tires and 3.55 g e ars. $700.

In my previous posts, I said that I had a 9" that I had originally gotten from PTC. But I see that they actually have it listed as a 9 1/2".
Lenny had told me that I needed a larger converter to get me where I wanted but that meant the elusive 11" core was needed.
Is it possible that the 9", 9 1/2", and 10" converters being mentioned here are in reality based on the same core?
Master, again and still

I run a Turbo Action 11" with 7/16 thread flexplate bolt upgrade (I couldn't keep the 5/16 thread bolts to stay tight despite being arp and loctited). 2800 rated stall as I recall.
Surprisingly, it has run a 1.37 60 ft.

I also run a Dynamic 9-1/2”. To the OP, I’d send it back to Lupo and explain to them exactly how the engine and car has changed. No one will know that converter better than them.

Not from what I have seen... but I ain't in the converter biz, either.

If I'm not mistaken, I think the 9" and 9.5" converter are the same. I remember my converter builder mentioning that, but it's been years ago. He's always built 9" converters for my stuff.
Brad...FWIW, my guy really likes ATI and buys a lot of parts from them.

I did speak with Sean once before the last round of engine changes. At that time he mentioned a stator change would be likely, but things have changed even more since then.
