Following is a post I made on a similar subject back in 2008. Of course, you'll upset all the Mopar purists that have to have their cars be 100% Mopar. I haven't pulled the trigger on this yet due to a couple of economic setbacks along the way, but still thinking really hard about it when the...

What year B-body? Generally, a B-body housing can be used in a A-body by simply relocating the spring perches and using a different wheel backspacing. My '69 Dart came with a B-body housing when I bought it from the previous owner. I'm simply going to have it narrowed so I can use it with the...

OK, so here's a question that maybe deserves its own thread. At what point does it make sense to look at a fabricated rear axle housing like the Moser 875? At the price A-body 8-3/4 housings are going for, it's almost cost effective to go with a fabricated housing. I was just on the Moser...

Check www.mopartsracing.com. The spacer is the same for both 727 and 904 trannys. You can buy the spacer/longer mounting screws kit as PN P4510054 at $22, or a spacer/filter/pan gasket/longer screws/etc. kit as PN P5249321 Filter Extension Package at $32

Just to clarify, this is why the 904 "consumes less power" or, there's less engine horsepower loss through a properly built 904 because of the smaller, lighter components and less internal friction. I'd suggest making your choice based on your intended use. Primarily race, then go with a built...

In all fairness, the $3300 Art was talking about was for a modified 200-4R and converter to live behind a strong 360. It also included all other mods (cooler lines, crossmember, etc.) and labor. The only thing it didn't include was a new driveshaft as stated.

Following is a post I made on a similar subject back in 2008. I haven't pulled the trigger on this yet due to a couple of economic setbacks along the way, but still planning to when the funds are available. Contact Art Carr directly at California Performance Transmissions, he's been building...

I'm seriously considering the 200-4R since Art Carr told me it will fit in the stock A-body trans tunnel better than the 700R4. I like the gear ratios better as well. Suggest you double check to make sure you won't need to do any trans tunnel work to make it fit.

I bet you're seeing the trans tunnel surgery necessary to fit a GM 4L80 overdrive automatic tranny into an A-body. I've got an alternate suggestion that I'm considering for my smallblock '69 Dart: an Art Carr built 200-4R 4-speed overdrive automatic. It fits in a stock A-body trans tunnel, is...

MoparPat - The final drive gear ratio in both the 904 and 727 trannys is 1.00, so no difference in RPM at 70MPH in 'Drive'. However, the 904 has less HP loss due to lighter internal components. The standard gear ratios for both the 904 and 727 are as follows: 904 trans 1st: 2.70 2nd: 1.54...

I was thinking the exact same thing, but then looked at the dates and found Ben's posts are from 2009. C'mon back, Ben. You're missed!!!

Hey, Vitamin c. A million years ago I ran a '69 340 Swinger with a bench seat and a B&M auto shifter on the floor. I'm 6'3" and didn't have any problem with the seat all the way back. My 5'3" wife didn't drive the car so there were no worries about a shorter driver. You can mount the shifter...

Just to throw another option in for your thoughts...see what local pricing might be on a complete B-body 8-3/4. If complete, you would get big bolt pattern axles and bigger brakes. You can run a B-body rearend in an A-body if you change the spring pad spacing. You can either get wheels with...

Scamper - FABO member swisswill has a current post ("Cleaning out my stuff...") for a B-body 8/3/4 for $50. Looks like it's complete with the 11" drum brakes. You'd just need to get it shipped from Michigan.

I can't speak for all B-body 8-3/4 housings without doing some research, but my '69 Dart came with a B-body rear end when I bought it from the previous owner. It just had some narrow 'roller' wheels on it. You can always buy rear wheels with bigger non-standard backspacing to center the...

JMO, but I think his price is high. Is it an A-body rearend or will it need to be shortened to fit? I'd want to see ALL of the receipts and know the shop that did the work for that kind of money.

Here's a post of mine from a year ago along the same subject but using a 200-4R instead of the 700-R4: I've been thinking about a 200-4R behind a 360 magnum crate motor in a '69 Dart for the past week or so. Talked to several tranny companies about it and finally contacted Art Carr at...

Not yet - still thinking and gathering 'build' funds. But I still like the idea.

Interesting. With a 28" tall tire, at 60mph the rpm is the gear ratio x 1000.

Back in the early '70s, I ran 4.89s behind a built 340/727 combo on the street with my old '69 340 Dart Swinger. Did not drive on the freeways with it, but what a rush coming off the line with that combo!

QUOTE=tomt966;401099]Anyone have comments about an Auburn posi unit? Yeah, a 'posi' goes in a GM. Mopars are 'SureGrip'.

I've been thinking about a 200-4R behind a 360 magnum crate motor in a '69 Dart for the past week or so. Talked to several tranny companies about it and finally contacted Art Carr at California Performance Transmissions last week. He estimates total cost including converter and installation at...

Inland Mopars Car Club built a '68 Valiant as a benefit raffle car this year using the RMS AlterKtion front and Street Lynx rear suspension. I had the opportunity to drive the finished car to 2 different shows and can verify the car handled GREAT. Rode like a dream on the freeways but was nice...

It's actually a new motorized Olympic event - the "1/4-mile pole vault".

A bunch? Have you see what center sections are going for on eBay? Good score!

489, 741, and 742 cases should all have the same external mounting points - yes the 741 snubber should fit the 489 case. Are you using stock snubber or upgrading to adjustable?

I just got that look that said "don't you dare" when I read this thread to my wife

xtreme - I had a cable-shifted B&M in my '69 Dart racecar a million years ago and remember it was zip-tied to a spare hole on the 'bellhousing' of the 747. Never did have a problem with it coming in contact with the headers.
