Mine was built to take up to 750 hp. I know a couple guys running 1000 hp Grand Nationals that run 200 4R and have no issues. They are plenty strong. I have just over 500 hp and I beat the living **** out of mine. Burnouts, rolling burnouts, track racing, street racing, etc... Mine lasted five...

What type of shifter do you plan to use?? I also used the Wilcap adapter, mostly because it was the thinnest letting me cut less off the cross member. Treblig

Here is the link when I did my 73 Sport. Pics of the cutaway on comment #85. And better ones at #110. 200R4 update

Not a problem. My 417 is probably north of 600 hp so we shall see how it holds out. They can be built to handle 1000 hp but it’s important to get them set up correctly. Otherwise they’ll fail along with the many others who have burned them up due to improper throttle valve adjustments and not...

If you go with the non-lock up converter you'll save some hassle with the converter engagement/disengagement switches and wiring. There's little difference in cost but much more fun to drive, for me at least. You will lose 1 or 2 MPG but I didn't care about that!! Treblig

Back to the gearvendors.

I'm rebuilding a GM 2004R for a guy down the street from me for his 69 Camaro. They are a good trans if you put quite a bit of money in them. One of the biggest costs is a billet or hardened forward drum. They can be built to handle 1000 HP according to Art Carr but that takes some doing...

Did you build a 2004r or a 700r4?

...your rear gear choices are fewer. If you only drive the car occasionally and never any long, long distances I'd go for the lower gear just for the fun of it!! But that just me?? That's why I went with the 2004R overdrive. 4:10/4:11 gears, tall tires and decent gas mileage. Treblig

After I installed the non-lock up 2004R (1800 stall) in my Barracuda I installed a cooler in front of the radiator. I also installed a trans temp gauge. It ran below 200 degrees all the time, I live in S. Texas so it's always very hot and humid: Treblig

I kept my original console and complete shifter in my '69 Barracuda when I installed the 2004R. I documented everything in detail here on FABO. I even did a little work to the shifter detents so that I could put it in 1st, 2nd, 3rd and 4th gear easily. Treblig

That makes a big difference!! I thought you were working on an A body. I don't know about any clearance issues you might have with the A500 or the 2004R but I do know that the 2004R does not require any cutting on the trans tunnel on an A body. treblig

No floor chopping with the GM 2004R!! I put one in my Barracuda and I'm so happy!! 3:90 gears and runs 2200 RPM at 60 MPH> Treblig

5275.00 for just a gearbox!!! If so I'll go with a tko 600 or 2004R.

Nope, wanted to keep it original in case I ever sold it (Chevy 10 posi w/4:10 gears, 2004R trans, 318): Good luck on your quest!! Treblig

If you don't want to cut the tunnel, you dont have many options. A GM 2004R is possible with minimal tunnel work and an adapter. My brother had one built to handle his 500hp 408 in his Dart Sport. A 518 typically requires more work because its bulkiest right in the crossmember area but some have...

Put a GM 200-4R 2004R, 2004R Transmissions, Performance 2004R, 2004R Monster Transmission, 200-4R Transmission Heavy Duty Performance with a Wilcap adapter plate. Wilcap Company Transmission Adapters Didn't see the 440 part. That makes things harder I think.

No matter what you choose you will have to do some tunnel and cross-member modifications. I haven't heard of anyone using a 5 speed but there are a few here that has used the 500 model Mopar o/d and the 2004r GM o/d trannys. You can use the search function and find a lot of info.

I wanted to produce a kit that would allow people to retain the torsion bar front end, without loosing any strength in the cars torsion bar frame area, while allowing a 6 speed transmission that could handle 700ft/lbs of torque. The swap over is an absolute amazing transformation!! Todd...

Thought I'd post a photo of the passenger side cut I made in the cross member to clear the 2004R. As noted earlier I won't weld the driver side cut until trans fitment is verified. Based on others posts, I went ahead and welded the passenger side cut, pretty sure it will be enough clearance. Not...

It’s laying around. I’ll probably toss it. Extreme Automatics builds them to 1000hp. I ended up with about 1/8” of end play on mine. Used some spacers provided by FTI.

I would go with the 2004R, it's worked out Soooo good with my car!!: Will GM 200r4 work with factory floor shift location? I recently switched to 4:56 gears and it still does extremely well on the highway, but I do use 29" tall tires!! treblig

Yea it looks machined. That’s why I asked. I’m debating over a 2004r or a gearvendors for an overdrive for my 67 Cuda. Don’t want to cut up the chassis or do a coil over conversion.

...Do you think I will need to change kits? Change valve body's? Is it possible to get what I want to feel. Ive had 727's, 350 Turbo trans and 2004R trans that all had good shifts like im looking for and they all had higher then stack stall convertors. Thanks for any info you can add. Thanks Rod

Oh man!! That's an easy one, 4:56 gears with 2004R overdrive...here's my current street machine: When I drive down the street all the other cars move out of the way!! Treblig

Thanks! I'll have to bookmark the site with that chart - that's some really useful info.

They are fine if you want to hack the tb crossmember and floor but there are tons of guys that don't want to do that and will pay that for a bolt in trans.

I chose a built 2004R for my '68. I would never go back to a non-overdrive, so any overdrive is a good choice in my book, but it is all dependent on what matches best with your combo, wants and needs. If you really want to blow your mind with modern upgrades, add fuel injection to your...

...transmission tunnels have to be modified to accept a overdrive. (especially the 727 base O?D trannys.) Quite a few guys have converted to a 2004r GM trans because of the small case size. Aparently folding the pinch weld on the lower part of the firewall and a modified trans crosmember are the...
