I know this is like kicking a hornets nest, but I'm gonna ask it any way, and go sit in the shade and wait for the stinging to begin.
I have run (and am still running it) a Turbo Action 17509J torque converter many years and have been more than pleased with it, but I know it's "old school" tecnology. I'm wondering if there is something else that would be better for my combo, that folks on here have experince with and would be willing to share. I'll list my como at the end, anyone with this type como experince, please tell me what you think would benifet my combo.

'72 Cuda, 3100 lbs w/ driver
SS leafs, MP 50/50 long rear shocks
4.56 Dana, Strange spool & axles
6 cyl torsion bars, Calvert front shocks
stock K member and control arms
Micky Thompson 11.5 X 29.5 slicks
727, T/A manual valve body, rev pattern
440 +.030", Stealth heads, 13.5:1 comp,
MP .590 solid cam, 1050 dominator,
2" Hooker super comp headers, VP 112 race fuel

This car is a true footbrake racer, running 1/8 & 1/4 mile, best time of 6.4X, 105.xx and 10.39, 127.xx. The engine has not been on a dyno, but calculaters show horse power to be in the 585 range and torque just over 600 ft/lbs. I currently shift at 6000 and go through the 1/4 at just under 7000 rpms. I have always felt the mph to be low for the ET, but not sure.
I welcome all sugestions,

Thanks,
Brian Dunnigan

Wow you are going to get 20 replies with 20 different converter companies....

I have run ATI and Trans specialties converters for years without any problems.

I also have a Dynamic that is one of the best footbrake converters I have ever owned.

Your VERY close on the ET to MPH... what do you figure
the RPM is for max torque... does the conv stall at
that RPM or a couple hundred higher... whats the slippage
rate on it... if those two things fall in line for
your engine why change,,, I run a T/A conv also and
I could use a bit more stall on my W-9 BUT it works
fine and I could run the risk of having it SCREWED up

Brian, give PTC a call, you won’t be disappointed. I have been running PTC converters for years.

Personally I wonder what a 4.10 gear would do for you. RPM seem pretty high for the combo.... just thinking out loud. We only run Ultimate torque converters. Lenny has treated us well over the years with an outstanding product and service. There are also a couple companies that I wouldn't do business with, but you didn't ask that....

well there is already one PosT reCommending a certain builder. everybody has bad days, but from what I have seen that's one piece I'd skip on. personal opinion learned from the pain of others.

Lenny at Ultimate

Brain i was running TCI 8' and i took it to PTC and they change it and it run the same and i put a 8' TURBO ACTION in and run the same i had a 446 with a NOS and went from 150 to 330 shot and the ran the fastest ET was 6.22 in my 3,120 at the time and JAMIE at pro torque converter said he could make a converter would run and he made me a 10' that he could do 14 ways it went 5,000 rpm and i put a 150 shot on the car a it went the 1st pass 6.01 at 118 and the 2nd pass it went 5.96 at 119 and he made me my converter for my 572 and he makes them for a lot 10.5 out law cars he built the converter for $ 750.00 and he knows converters and he is in TENNESSEE 1-423-462-2771

I had Lenny at Ultimate build me a custom converter.
I told him what I was looking for, and sent him the specs for my engine and car, and he sent me a converter that did just what I asked for. I think he would also make adjustments to the converter if needed. It was not cheap, but It was nice working with a professional and getting it right the first time. In my earlier age I bought several cheap converters and had some that were OK, and others that were junk. I finally got a nice Dynamic converter that worked pretty good, but sliped a bit in highway driving. The Ultimate converter I had built is tigher when driving in town and on the highway, but still stalls at a higher RPM then my dynamic. Because it is tighter, it does not hit the tires as hard at the track, but I was not looking for a track only converter.

Your combination is very similar to mine, i'm at 3200 my edelbrocks are ported with a 950 holley, i run an ultimate 9", stalls about 47-4800 i think, i shift around 6000 and go through the line at 6500.
I reckon there might be another 1/10 in mine.
If your heads aren't ported, i dont think you'll do much better, your mph is in line with your et.

I have a Ultimate in all three of the cars I footbrake. Big block e-body, small block a-body, and a Stock Eliminator Volare with a small block. His converter was a improvement over every converter I had prior. Very consistant and dependable.

Best, spot on converter I ever had out of the box came from Lenny at Ultimate. Great service as well.

I am running A 8" coan and seems to be working good! Good customer service.

Got an 8" from Lenny for our Dart.....can't wait to try it.

ATI Treemasters have been great for us, and I wouldnt hesitate one bit to call Lenny at Ultimate as well. A good converter is the best money you can spend on ANY combination.

The wallace calc shows your speed is right in line with your et, maybe a power upgrade might be a better idea.

I know you are across the country but Continental Converters in California is one of if not the best at getting a converter to work with your combo. Give them a call.
