Got a question for any well anointed tf 727 guy.

While we have tim p's engine out for the last fix I want to have the tc gone through and have the overrun clutch replaced. One potential cause for low stall speeds is a duff converter over run clutch. Also want to see where in the scheme of all things IH the converter stall speed is. Much unknown about model year changes in the emissions era.

I'll get to the point, who is a reputable tc rebuilder? I could get anything you need for a race car but for a stock tf 727 app. I have no good avenues.:confused:

Whoever you might use locally for torque converter reman can do this...it's a simple "exchange" for the specification that yawl wanna use.

The "specialty" performance torque converters are a simple "side line" for those folks usually under a completely different "brand" for marketing/distribution, and pricing purposes. It's run of the mill tc remans that drive that industry, not the specialty stuff...even in that hot bed of carparts specialty...lalaland!

Simple reman torque converters are available off the shelf in several stalls for the sii app (or any IH/727 app). Locally, the remanner wholesales those in the $85>$115 range to local independent garages and tranny shops.

Maybe contact these folks for a start? Down in vista near sandeg:

dalenzie torque converters - highest quality
 
The input on the tc on my Scout is pretty grooved up. Id be afraid to use an autozone tc or seal...I don't want to tear it back out in 6 months. Where's a good place to get a "mild" performance tc?? I'm gonna run 3.55 rears, 33 inch tires, and a fuel injected 392 with a rv cam. I plan on mostly street driving with the seldome trip up the mountain.

Thanks

This past Wednesday, I assisted a fabrication shop over on the coast in completing a complete engine/trans swap in a mint '67 t-all. A seriously hotted up pro-built 392, with one of our ihon 727 trannys with 4.10 axles in front of a np202 box. The trans includes a B&M parts package internally along with appropriate shift reprogramming done on the valve body. A 30,000lb. Prf tranny cooler completes the package.

Ihon put together a complete transmission swap package with all parts (down to the converter bolts) needed to go from a stock 304 in front of a t-19 with a beefed clutch to the 727. It's pretty much a bolt-in except for fabrication of the primary driveshaft (shorty) and the exhaust system. Included a complete lokar throttle cable/kickdown setup which made the installation a breeze.

I had a local converter builder do an 1800rpm stall unit for this one which is absolutely perfect. This rig is owned by a very knowledgeable "gearhead" who has owned it and towed an airstream or a car trailer to shows all over the u.s. Since the early 70's in all kinds of driving conditions. It's now been purpose-built as the ultimate trailer dragger for the owner.

The best is yet to come...a fresh NP205 transfer case is sitting on the bench and will be installed as soon as the gearvendors overdrive unit arrives, it's stuck in the rear of the 205.

After test driving the rig and verifying stall speed, I'm certain we made the right choice of converter.

I have these converters done locally by a builder who does business only with wholesalers, transmission shops, and professional garages. They operate no website, and don't use email either, don't even have a sign or address on their building.

Jeff also has a similar converter builder in his area. We can supply you with a converter from either source, call ihon for a quote, you will be shocked at how reasonable the cost is...but shipping weight is about 25lbs.

Thanks for the bizz!

And...make certain ya fully engage the converter snout to the pump and the reaction shaft support and input shaft before mounting the trans to the engine!

The converter body must sit at least 1/2" inside the trans bellhousing when it's pushed all the way back and all three "line-up" points are engaged. Then mount the trans to the engine. When you pull the converter forward to mate up with the mounting bolt pads, it should come out about 1/8">1/4" to mate the pads to the flexplate.

Cool thanks for the tip, where's a good place to get a quality input seal, every autozone seal I have on my terra leaks! Grrrr....

out of curiousity what was the turn around time for this? I need a new converter (or rebuild) and plan to go with a local shop. If turn around isn't too bad I will keep my money within the vendors that support us.:thumbsup:

Turnaround time for the torque converter supplier we use up here???...about an hour! They are on the shelf always.

Turnaround time for the suppliers used in norkali...call Jeff at the shop and ask...530.268.0864.

What I May do is install a custom stall converter. I would like about a 2000 rpm. Would your local shop have this on the shelf?
I could just stick with a stock converter as it works "ok" and the added heat of the custom is a negative......
I could go either way.:skep:
