small block transmission help

[71chally416]

Soak the new clutches overnight in tranny fluid before you install them.

Also spend the time during assembly to air check (40 psi or so) both clutches and the servos for correct operation. Will save you headaches later on if other problems pop up.

Well turns out that the 727 I had a line on is really a 904. So I am on the search for a rebuildable 727 that doesn't need any hard parts replaced.

You're in the bay area right? If it hasn't already happened this month, go to the mopar alley meeting and ask there, maybe someone will have one or know where to get one. If you know people in the club, I would ask Shelby Wright. I bet he would know who has one.

Sucks that pretty much anything you get is a crapshoot unless you know the seller well. Found a couple on craigslist that might be worth looking into.

Here is one (with an engine if you want to go that way) Closer to Redding:

This is a complete engine and transmission that were removed from a running until wrecked Dodge 1/2 ton pickup. According to the block casting number it is a 1976-1980 LA-series 360 four barrel engine. The block code is 4006830. The intake manifold casting number is 3830945. The carb is a remaunfactured Carter thermoquad. The engine is complete from the fan to flexplate and from the air cleaner to pan. The exhaust manifolds are still installed and I believe the starter is there as well. There is an alternator, power steering pump and an air pump still in place on the front of the engine. All of the linkage for the carb and the transmission are still attached. I ended up with the engine/tranny as a result of a multi-transaction trade and have no use for it. It has been stored indoors since removed and should be in good serviceable condition. I will separate the engine and transmission and sell each individually. The price for the engine is $300 and the transmission is $100. I am open to trades so make me an offer and let's see what we can work out. Email or call Terry at 530 990-1642

Thanks. I am talking to the guy in sac right now sounds like it will work. It's funny you mention Mopar Alley as I am the president. We are having the club Christmas party this weekend and I will ask the members there. I know Shelby, he should be there and I will talk to him.

Is there another source for the reverse band? The website for transmission parts is currently out of stock.

Perfect thanks.

Small Block street car, 904 is the way to go... 3500lbs or less..
Will last just as long as a heavy 727 and the low gears are cheap as heck , you should be able to find in the salvage yards..
904 much quicker too...
Lever: my choice a 4.2
 

[71chally416]

  TOTALLY. I guess we're the only two here that know that. Seems like a lot of hassle just to go slower to me. 

[72hemi]

Normally I would agree about using the 904 (as the first one in my Challenger lasted almost 10 years) but I have gone through 2 904's so far this year so the switch to the 727 is partly mental, but long term with my next 340 another "replacement" 904 won't last.

[tactransman]

Most people on here don't care so much about running a tenth or two faster in the quarter mile,they want longevity and hassle free. It cost the same to rebuild a 727 as it does a 904 and they didn't put the 904 behind any big blocks from the factory for a reason. Stock rebuild against stock rebuild,the 727 wins ............. big time. 904's like to break converter hubs too, since they are so small and the pump's working harder with shift kit and manual VB pressures.

So ..... to each his own,pick want YOU want for your application. 

[72hemi]

  My closest dragstrip is about an hour away and that tenth or two doesn't do me much good around town. I just want something that I won't have to mess with. Got all of the parts ordered and on there way except for the kickdown lever, still have to go to a dealership to order that, and I am going Sunday to get a transmission it looks like. Also I got my copy of that transmission book so I have some reading to do. Hopefully my car will be back on the road in a few weeks.

The "tenth or two" thing is something I would dispute. That figure has been quoted so many times now I guess it's now the Gospel. I don't know how many of the people using that figure ever actually did A-B comparisons. I know my car went at least 4 tenths quicker with the 2.74 low-geared 904 with no other changes. That's kind of a scewed comparison too, because the 727 I removed had a 10" 3,000 stall convertor and the 904 vert I installed was a stocker. It could have went much quicker than it did, or closer to a second with the improved MPH it had (109 vs 104) but I was handicapped with the launch RPM of the stock vert. It launched at 3K+ with the 727 and 2K with the 904 and still had a better 60 ft time with the 904. It's about accelerating the mass connected to the crankshaft. A car will also get better mileage with a 904, no doubt. Less parasitic loss. The lower the HP and the more challenged the motor is (I.E. - the smaller the engine, the lower the compression, the less low end TQ the motor has) the more it will help.

That's why Chrysler installed the 2.74 low geared lock up 904's in the emasulated smog motored cars and Jeeps, to help them accelerate better and get better mileage. You won't find a single Automatic equipped vehicle made today with the 1st gear ratio that an old stock 727 has. It has a good ratio for a big torquey 440, but it's the suck for a heavy car like an E-body with a mild small block.

Good Morning 72hemi,
If you really want to solve all your problems go with a 833 4spd. I put one in my Cuda last spring and it's so much fun to mess around with, but going to the track and running some of those Muscle Car races is a different story. You will need slicks, scattershield, drive shaft loop and hope you don't break anything. It's fun and a little harder to get a hold of the track...
I only go to the track maybe 4 times a year now...

But what ever you feel comfortable with,  go for it!

They are all (904/727/833) good pieces......
