GM knows a good thing when they see it---Gm and ford have been paying royalties to chrysler since the 60,s for developing technology(727) in automatic transmissions----yes i know when the diesel came out chrysler bought turbo 400 torque converters from gm---but alas allison even used the turbo 400--- (it was easier to just buy it instead of going into developement)-----can any of you gm/chrysler technophobs tell me if chrysler has been paying royalties to GM for their transmission innovations?---if i remember the article right 17 manufacturers world wide have paid royalties to chrysler (727) for the use----bob

Is there really such a thing as an automatic overdrive?

Being an Olds guy as well, I know that a lot of people use the 200-4R in their Cutlasses behind 455s with great success. An Olds 455 is easily in the 500+ lbs./ft. community. It's all in how it's put together. As mentioned earlier, check with the Turbo Buick guys. They are running sub-11's in 3500 lb. Regals with these trannies.
Another plus to a 200-4R over the 700R4 is the gear spread. The drop from first to second is closer, being better for a big-block, with a slightly better O.D. gear.

The Man since I was a little boy is Art Carr. He, however, cashed in on his name and now if you want an Art Carr transmission you go to:
http://cpttransmission.com/
where you can buy his version of the 200. I've been looking at one to go behind a 455 in my '65 Cutlass S in place of the Super Turbine 300. Looks encouraging. Remember that you have to have resistance at the other end to make a component actually see the torque.

Also, unless the 'vert is going to get massive frame reinforcements, it'll be twisted into pretzel shape long before any real driveline damage is done. I say this based on seeing twisted bigblock E-bodies at the drag strip back in the day. So I believe the emphasis on strength of the transmission is more a talking point than a real need.

So, the bolt in Keisler kit, which I believe uses a 4L65E, is a winner. The runner up goes to a make-it-fit-yourself 200-4R.

Dan call Pat at SMR in canada. He can custom build ya a 518 and you will have to have an adapter kit to bolt it to a big block.

Pat is good people, very easy to deal with and beats on his auto overdrives in his own race Dakota. He will go over any details you might deal with and help ya right along.

they used it before they developed their own----it seems to be common knowledge down at the torque converter shop i was told thats why mopar picked it up--because it was previously used and proven and was cheaper for mopar to buy instead of going into developement on their own

A bit off topic, but the new book by Andy F had an interesting idea on chassis stiffening, of using two floor pans? I never heard of anyone doing that, but it sounds like a good idea (along with subframe connectors) in a convertible?

That is an interesting idea, some demo derby guys double-up door and fender skins like that.

I'm not sure what to think of doing that to a 'keeper' car unless it never saw rain or temperature swings / condensation.

Allison was a GM subsidiary from 1928 until 2007, when it went private. The TH-400 converter was in the corporate family.

The SMR shorty should work fine with that engine combo. No hacking other than shortening the driveshaft a few inches. All the factory lines/linkage bolts right on.

Yes, It is a Gear Vendors unit. Looks like they came up with a shortened version of the adapter housing with matching parts. If it fits as they say, its a nice deal. Never saw one.

It is a GV. It uses the shorter truck 727. When I finally pull the trigger for OD in my 66 C-body that's the choice. I already have the trans from a 4x4 that used a divorced t-case.

A buddy of mine in Sweden isntalled the SMR setup in his 65 300, I think he did a writeup on the Drydock. He goes by 'unclejoe'.

BTW, love the dragstrip vid of your 66 NY that I stumbled across on youtube a while back!

Cool idea...but $3k...cmon....




Price a gear vendors it's not much different more.

Any Od short of scrounging a 518 from the junkyard and backyarding it yourself isn't cheap .... like you ....

Thanx. I haven't been back since. The best that day was a 13.92. 60 ft was a no traction 2.23. I've gone from a 2.76 SG to a 3.23 SG and I need to put some real tires on it. 12.99 is the goal. It weighs 4800.... Yeah I know

The SMR trans uses the Gear Vendors Shorty kit. http://www.gearvendors.com/hrdodge3s.html
