Out put shafts of 3 speed 6cyl vs V8 and RAT vs RAN

[Gas Pig]

Are all stock 3 speeds' output shafts the same? I know the intermediate housing are different from 6 cyl... being shorter compared to a V8 one. I would guess the difference of the lenght from I6 to V8 is all in the spud shaft and it the tranny itself?

Also RAT vs RAN... I believe the only differences is gear ratios of 1st and 2nd gears. Wasn't the RAN used on the I6 and RAT on the V8?

Thanks Jeff

Output shafts are different lengths and are not interchangeable between V8 and I6 transmissions.

"... RAN used on the I6 and …"
generally, yes, but…
a more specific Q will get U a more correct answer.
the below may help but as above - what's yer Q?

Yeah what I'm trying to figure out what options I have in transmissions when I do my I6 300 build. I currently have top shift 4 speed OD drive trany out of 95-96 F150. It already has the advance adapter kit installed for a D20... but kit is so a V8 intermediate housing. I wonder how that would with T-case shifter location while being used with I6 motor.

My other choice of trans might be a AODE but once again would it set the transfer case to far back with a I6 motor?

Thanks Jeff

Hi Jeff,
Sorry? May B start @ the beginning, I'm a lill soft & therefore can't follow U...
U have an EB?
It has a 300 in it?
U don't know what transmission to put in?
It's a very l o n g engine -

Yes I want to build a glass body EB with a 300. I know of a couple members here who have made it fit. Yeah I know 300 long and tall and there is a handful of frame mods and firewall mod if I go with EFI.

As for the trans issue... the two guys who did the 300 swap one guy used a NP435 and the other used a stock 6 cyl 3 speed. I'm wanting to go with a OD trans. The one I already own is manual 4 speed OD out of 95 F150 that has been adapted for a stock D20 and bolts to stocks 302 bell housing. Now my concernes is the advance adaptors kit I used a the 4 speed uses a V8 transfer intermediate housing.

My original question of the post was the is the output shafts of stock trans V8's & I6 are the same lenght. My hope was that they were and the difference in the lengths are all in the intermediate housing and spud shafts. Because I could swap out the V8 intermediate housing on my 4 speed for a I6 intermediate housing. But I guess I can't because output shaft is longer on V8. My other thought was AODE but I think is going to be even longer then my 4 speed.

Just trying to feel out my trany options for a 300.

the 300 has the same bell housing as the 302,
those same trannies will fit.

"...Output shafts are different lengths and are not interchangeable between V8 and I6 transmissions."

ur 3.03 will bolt up to that 300 I6 and the D20, no changes from what the bronk doaner had. Many use the NV 3550, NV 4500, ZFs for a 5 speed. If ur going from skratch - new frame'n chassy, I'd suggest a driveline design for the application rather than avaliable prts. It kinda gets back to my 1st post:
"...a more specific Q will get U a more correct answer…."
A build is best excequted by answering the application question throughly, doing extensive research on how to best meet that use, and never deviating from the plan while in the process of completion. (Sorry for spoutin off so much but I've seen quite a few 'messes', 'more $ than brains', etc).

What is the final application - I know it includes a 300 I6 (like puttin a 4BT in) and Glass body?
AND a 5 Speed (may B?)?
rd conditions?, specific off rd use, 2lanes?, freeways?, stop'n go traffic?, city, etc?
Good Luck,
Keep us posted as this develops….
