My son and I haven't had a problem with stock input, output shafts, or stock case. Both make over 850hp. In fact I cant think of anyone I know that's had an issue with those components either.

Besides the drum exploding what will total a stock case handle?? I am putting well over a 1000 hp through a stock one and had to upgrade some internals like the drum and planets.

how can the case work with the 727 plus all the OD variants ? i thought where the OD bolted up, there are different hydraulic circuits, or are these blocked off somehow to allow this case to be used as a 727 ?

I wondered that myself. It would be nice to be able to put a 518 behind a 440 without a bunch of cobbled up band aids to make it happen but the price point this piece will land at IF it ever gets made will make that a nonstarter.

I am very interested in an SFI 727 case, and would be a buyer, even at $2k. My '64 Dodge has a Powerglide in it (since the mid-90's), and is still miserable to work around with a bell shield and a blanket. Being able to eliminate those two items, and put a 727 back in the car (which is on my to-do list) without cutting the floor would be awesome. I do not want to cut the floor out of the car, as the car is kind of the poster child for 727 explosions (Yes, it's THAT '64 Dodge).

I suppose that is true in some parts of the country but around here I had a hard time even selling bare 727 cases. I have 5 or 6 big block cases that I tried to sell and people didn't want to pay much for them. Hard to get $100 for one since you can buy a complete trans for that on CL. (used and in unknown condition)

Hardcore Mopar guys will want a new SFI case. I doubt the mfg will sell a ton of them but they'll sell enough to make money on the deal. The smart money would be on selling the case to other dealers such as ATI and the big trans shops rather than selling them retail. That lets everyone make some money.

If they are a fair price, I will take one. Never subscribed to the power glide controversy myself, so this makes sense. Hopefully they put some thought into it for bell housings, and relocating the breather, and even adaptability to a GV's....

If you look at the case where the valve body bolts up at the rear, the 3-speed and the OD are the same, depends on how the passages are routed into the tail from there.

It looks to me like it could be machined for either or, but not both.

I would take one when available...

The market for these is most likely going to be the diesel truck arena and some for the drag race market - the diesel market is ramping up big time. extreme mopar drag racers probably have already moved to the Reid case and a turbo 400 or glide - just way more hard parts available for those set-ups

curios on the weight of these cases , compared to a stock case.

If a guy already had a built 727, this is good insurance beefing up the case. IMO the thing I hate about my RMVB shift pattern is being stuck in 3rd with no handy neutral if something breaks. If that could be changed back to a normal pattern and keep the brake I might keep the 727. That adapter bell would make changing between a SB and BB easier also, as I would have to replace the case anyways to put a Gen 3 with it. Or get a glide for one.

"Clean Neutral" and "Safe Neutral" VB's have Neutral directly behind 3rd. Requires a shifter set up for them.

Me thinks I have clean Neutral when I press "N"

Best I can tell they've been developed for the diesel truck market. The bell housing mount pattern isn't the same as the ATI or Reid bells, they'll be offering their own bell housings as well. I know nothing about the particulars of Cummings diesels, I have no idea what the bell housing pattern is, so you might be waiting a while to see something that fits your SB or BB. Hopefully they offer something that takes the aftermarket bells we have already.

-itis, i wondered about that, and i think i may have even asked about it, but [as my mind always works - or doesn't ] i forget what the answer was, or is. mr. kunkle may have given me the answer.
please refresh me sir. the pushbutton function - clean neutral.
is it possible for the button to bypass 2nd and first fast enough from drive to effectively have a "clean neutral" ?
TIA as always.

I had A1 converter in my old 1963 M.W. stocker and had them freshen the tranny, they installed a RLBA valve body in it without telling me about what it would do going into neutral, I had to stop punching neutral at the finish line so it wouldn't grab low gear
I hated that V.B.
I had a spare T/A RMVB in the other tranny and swap it out after that race

The PB shifter moves the manual valve through 2 and 1 before arriving at N, same as any lever shifter.

Hey, any new part for a mope is a good thing!

For sure a big improvement for the 727. Great for class racers that have to run a mope tranny.
