If no one provides an answer in next couple of days, I can take some measurements.
Just need to do some musical cars.

Poster has been in a struggle and I doubt any one will help him. Simple center to floor measurement is all he needs.

Thank you, I appreciate it

That measurement will vary from car to car depending on what the torsion bar tension is and which front and rear tires are on that car
Your aftermarket hand made K member measurements may or may not be close to stock

The ride height would change, but the engine and transmission wouldn't shift around since both crossmembers and floor pans stay the same

Unless there's been damage in the past that altered things? The body section of the FSM gives that kind of info. This is for a 71 E body, I don't have it for a 73 and not sure how different they may be,

Does anybody know the correct centerline measurement for an e body 4 speed? Maybe from the center of the tailshaft to the floor pan? My engine is sitting low in the back and I'm trying to determine if the engine is too high or the transmission is too low.

Thank you, I appreciate it

Ok I have a 70 Cuda with a 426 hemi 4-speed. The block is one of the hemi's that has the factory big block ears and uses wedge motor mounts instead of hemi motor mounts so they bolt up to the factory k frame the same as a wedge. So the engine and transmission are both installed in the factory location with factory mounts.

I went out and crawled under it and the best I can measure is it's between 2 1/4" to 2 3/8" from the top of tail shaft to floor pan. Floor to center of tail shaft (center of yoke) between 3 1/2" to 3 5/8".

Hope this helps

Does anybody know the correct centerline measurement for an e body 4 speed? Maybe from the center of the tailshaft to the floor pan? My engine is sitting low in the back and I'm trying to determine if the engine is too high or the transmission is too low. Both engine and transmission mounts are brand new. Stock transmission crossmember and stock. al debevec hemi k member

what do you mean by " My engine is sitting too low in the back "

What exactly do you think is not at the right height/angle , the engine or the trans ? If you have the stock trans crossmember, with a stock mount, and a stock tailhousing on the trans then the trans is where it s supposed to be, the engine mounts being not in the factory location will cause either the tailhousing to angle down if the engine mounts set the engine higher or the tailhousing will angle upward if the engine is lower. If the mounts move the engine to one side of the other the tailhousing will angle in the opposite direction from where the engine is shifted. There isn't a lot of room between the centerlink and the oilpan , assuming you have a factory pan so that might be a good guage as to the engine being high or low , a piece of 3/4 think pine ( 1"x?) is what I usually stuff between the center link and the pan if I have to hang the engine without a trans on it for a short amount of time.

Your engine is not mounted in the factory location , that is not how a Hemi was attached to the K frame on any factory built Hemi car .
