Personally Ive had better luck with Dynamic than anyone else, as far as building and working like I thought it should. Since Ive moved back to Kentucky though Ive used BTE to do a repair on a starter ring gear of the old Dynamic and they were excellent to deal with, seems a large majority of people in this area think they are by far the best. All I know is lots of people really like them, and that they are very reasonable on pricing.

FTI only shows one (1) item for a 727 trans, their 9.5" street/strip converter. Is that correct?

Sounds like Edge Racing is the GER of the 21st century.

Mine is going to Dynamic for the new build. Been dealing with Frank for 35+ years and can't stop now.............

I have one 8” converter 6200 stall that has some slip, but will print off 1.34 60 times and 6.13 1/8 times by the notebook full. I attribute the consistency to my 3rd place finish in the Hot Rod Heritage Series 2 years ago.

My other 8” is tighter and 5800 stall. It can dip into the high 1.2’s on the 60 and has given me a best 1/8th increment of 5.94. Prob is that it can vary on launch and isn’t nearly as predictable. I bought this piece just to shut a guy up that thought he had me covered as he had intel from my slo piece.

Good thing I have all these piled up next to my 727 as I’m switching over to a 904... dumb...dumb...dumb...

Hopefully I can help inspire you, just think of that glorious feeling you will have when you rip off that 1.35 60' and a 6.14 et with the new combo Who is supplying the new converter?

That’s my goal.... I like to spend a lot to go back in time! I have Ultimate converters stacked up like cord wood. It was actually a really old Dynamic.... so old Lenny was probably still working with Frank when it was built. Had it updated for this combo + the a500 pump drive conversion.

ATI is still very popular with the stock/superstock crowd.

I was gonna say why not ATI? The local guy that builds my converters and transmissions has a very close relationship w/ ATI and uses a lot of their parts.
Atlantic Coast Converters in Conway, SC, is who I use. Almost everyone around this part of SC and NC uses them.

While I have not got anything from them recently I have used Turbo Action for years. I had one converter that sat on the shelf long enough to be out of warranty when I used it. After a few races something let go internally and they still warrantied it.

As I understand it Paul works part time now and he is who I would want to talk to. I think he comes in at 1:00 pm four days a week.

x2 on PTC. Nothing like you guys are running, but they worked over a lock up 904/a500 stocker for me, tweaking the stall so it is right where I wanted it, put on the "d" drive and big bolt lugs. Does exactly what I need it to, this is on a 408.

I would suggest calling A-1, and order a 8 inch converter. I have a 8 inch tight 4800 RPM stall converter in my 505 stoker, with 4:10 dana. Nothing but fun, works so nice, perfect drivability on the street, no slop. Stomp on the gas and holy crap, it flashes to 4800 in an instant and takes off. Very good product, no complaints, custom made per my dyno sheet, and car specs. May be a little more $$ than some, but is worth it in my opinion. Give them a call, you won't be disappointed. Very nice guys to talk with also.
FYI...Dave Smith at Pro-Trans built my 727, and recommended that I order a 8 inch A-1 converter. I trusted his recommendation, glad I did.

I had A1 work on my nine inch Continental converter and Mikes Ultra Glide after it broke. It lasted 12 runs before it broke again
I paid them to fix it again and it has lasted a little bit longer this time, so far
If and when I have another glide converter built it will be a ATI
I have used Dave at Pro Trans for years on my Mopar trans. cars
He is building me a all out 727 now for one of my customers street and show car with a 800 HP pump gas 572 EFI Hemi motor, hopefully he will be able to supply me with a good converter for that car also
OP, buy the best converter you can get
Not the cheapest

Many good companies out there and of course you will get about 20 different opinions on what everyone likes. I guess it just depends on what someone uses that works good for them. I love my 9.5 Dynamic that's been in my car since 2006 and still working fine on the street and track. Ron

Just a thought
IF you footbrake
The fastest converter may not be the best for hitting the tree--Tighter makes it easier to nail the tree vs loose ( which is usually faster 60 ft etc)

My favorite two are ATI & PTC. I used to run a PTC 8" 5000 nitrous convertor in one of my old Pro street 69 Charger for 5-6 year on the street until I sold the car. Totally street friendly until you mashed the throttle & then it would do what it needed to do.

I currently have another PTC 9.5" 3800 convertor in my street driven cruiser 70' Charger with well over 30,000 street miles on it & is about 10 years old now without any issues.

I also have another PTC 9.5" 5400 Nitrous convertor in my 70' Hemi street/strip 70' Challenger. No complaints from PTC from me.

ATI is usually more expensive than PTC but so many of my buddies are always returning them back & forth between ATI & Ultimate Convertors to adjust the stall up or down several hundred RPMs to get them right.

Thanks Al, as always I appreciate the info.

I did not know where the stuff went, the kid Peter was trying to put something together when they 1st closed. But that obviously did not happen. [/quote]

Glad I clicked on this thread. Kris built me a converter a couple of years ago and it turned out to be one of his last. Great guy, great product, great price. I appreciate the update.

I learned the hard way on that way back when. Broke one GER(it sound like a box of glass), they replaced it and the replacement had 13% loss. I've been running a PTC for quite awhile.

I've had a UCC in mine since 2005 no issues...

One of my buddies tried a 10" 4000 GER in his turbo 400 in his 68 Pontiac because they were so cheap. He got lucky. It lasted many years with abused street/strip miles in a 10 sec all steel street car. Still worked great when he just sold it a few years ago. The car has changed hands & is still going strong today & is back up for sale again now from new owner #2.
