If they can't quality check their add I'd be reluctant to give them a tranny. i,e, "GET THE OVERDRIVE CONVERSATION FOR YOUR TORQUEFLITE BIG-BLOCK!" Conversation, really?

Add? really?

See, it can happen to anyone can't it?

They say there is always the exception that proves the rule.
Don't be the exception.

Transvestites are people too, so they should neither be sold or given away.

Sounds like a 518 to me, maybe they just do the bell housing mod for you?

Most people (shops anyway) hire people to run their websites, so I wouldn't exactly hold that against them. I was thinking more of just getting a case from them and having my builder build it.

Yep, from what I understand they cut a 727 bell off and graft it to a 518 case. Thought about doing it locally but looking for input.

Ultrabell bellhousing.

It still doesn't solve the problem of the girth of the 518 interfering with the floorpan and torsion bar crossmember...

That's why I am looking for input, what started this is a picked up a Aug 08 collector's guide and it had an article on it that claimed a direct bolt in with no major modifications to the floor pan. They use a special tranny crossmember and shorten the drive shaft but don't talk about any mods to the floor or tortion bar mount. Seems like this would be popular knowledge at this point IF it were true but if no one here has any direct knowledge of it one would have to doubt the claims.

As for 25-30% increase in MPGs, a lock up will give you close to 10% I think so a .60-70 to one ratio would help and keep in mind 25% or 12 MPG is only 3 MPG. It would be basically like changing from a 3.91 gear to a 2.94 gear.

I think your estimate on the gains with the lock up converter are optimistic. a 10% gain? I don't think even in the absolute best case scenario that you'd get more that 4-5% from the converter unless you go from a 5000 stall unit to the lock up type.
The RPM decrease percentage does not always directly translate to the equal gain in mileage.
Example: If you reduce cruising rpms by 25%, it does not mean the mileage will increase by 25%.
I had a Gear Vendors overdrive in my car for about 2 years. I ran a 3.91 gear through the .78 OD. The final drive in OD was 3.05. The best mileage I ever got was 12.81 and I was happy to get that.
I made the same trip a year before with no OD but with a 3.23 diff. I got 11.3 on one tank, 10.8 on another and just figured an 11 mpg average. The comparisons may have been skewed a bit since I drove real easy with the GV to see what the gains would be with the overdrive.

Mopar346..
I put an A518 non-lock up into a customers car (1972 Plymouth Duster) and the customer was very happy with the results. I didn't have to cut any holes in the floors, I just had to make some hemispherical indents in the floor/tunnel area for clearance. I had to cut out the center of the torsin bar crossmember and I replaced the support with an 1/8" piece of plate steel formed to shape and had to make my own crossmember. It worked so well that I am going to install an A518 lock up style into my 1971 Charger with a 383 engine.

If the tortion bar mount has to be modified then it's a no go for me. Oh well, just hoping that's all.

Thanks for the info.

Frankenduster,
And yea, 10 might be a little hopeful on an increase from a lock up. I wonder what improvement you would have seen if you stayed with the 3.23s?

Well, I had to cut the top center out of the torsin bar frame member because of the size of the overdrive section being so large. I don't know if you would have to do that on a B or E-body car for sure... but I would guess you would have to.
