C4 transmision length. case fill vs pan fill

[OneTonGoldfish]

I've read online that the case fill c4 is almost 6" shorter than the pan fill. Is this true????

I am working on a project that is extremely space limited so 6" less on the length would really help me out.

No. There is a small difference like 1/4" or so.

That's so strange, Ive found multiple sources that list the same 6" difference....I may have to look for a short shaft powerglide now

x2 on what viper said.

They are measuring the whole trans with 2wd tailhousing, a shorter tailhousing may have been more common on one or the other.

FWIW advance adapters has a shorty adapter for the c-4 for the atlas, must be full manual but might help on the length.

There was a fixed yoke short output 2wd version used in trucks and vans that was about 6" shorter than the car version. Apparently used '67-'71, but I didn't spend much time researching that.
Not relevant for a 4wd application.

Thanks for the info! and sorry for the confusion; this project I'm doing is not bronco or 4x4 related. I am building a Bonneville drop tank racer like this:

Well that's way cool, what's your drivetrain plans? Small block ford/auto/quickchange? Flathead? Early hemi? What class rules will you have to meet?
