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

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.

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

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 I called AL who converted the crossmeber right when I noticed the problem. It's the original factory crossmember that came on the car, he just removes the small block brackets and rewelds stock hemi brackets on with a jig that's built to factory specs. I guess anything is possible, so it could be off, but everybody online praises the guy and his work and I've never heard anything but how great his work is and how well everyones engines fit with them vs using the Schumacher engine conversion mounts. I don't see how this measurement could be different from car to car, other than slight variations of the floor pan, or how the tires or torsion bars could affect this? The ride height would change, but the engine and transmission wouldn't shift around since both crossmembers and floor pans stay the same

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. I can't really help with the measurements as we run an auto but I had a similar problem on my '74 Challenger. The box section where the trans mount attaches to was pulling away from the unibody, the welds have given way probably due to engine torque and / or a few hard landings from big wheelstands. I welded it back on as best I could but still had to shim it under the trans mount pad to get it right, IIRC it was around 1/4". HTH's PS. My aftermarket K member also lowered the engine as my 2 1/4" headers will attest too

Simple center to floor measurement is all he needs. 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 Mike

Thanks you very much. I pulled the k member back out to try and see if there was anyway I that I could modify the engine mounts. I'll get a measurement when it's back in. Thanks again

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 . John You're mistaken. The factory hemi and 440 wedge engines are mounted in the same location. The only difference is how it's done. The hemi doesn't use a different K frame to change it's location it uses it and different motor mounts because the exhaust manifolds won't fit with wedge mounts.

As said in the other thread you should pull the pass side valve cover off and either remove the left header or pull out the steering box and get the engine down on the mounts without any spacers to see if the engine/trans are remotely where they should be .

Here's a picture of the transmission crossmember. It's hard to get a good picture of it since tge car is only on jack stands. The measurement from the top of the tunnel of the floor pan to the center of the tailshaft is approximately 3 1/2"

According to the other members on here who measured theirs, this is inline with their measurements although they vary about an inch between each members car.

That 1" difference might be because my car was a factory 4-speed and the other car was a factory automatic so the tunnel height might be different???? the tunnel where the measurement is the same Auto or 4 speed, the floor pan used is the same and the side ofthe tunnel is cut open to clear the shifter . A 1" difference is a lot and that would be changed by how high up the engine is at the K frame.

This brings back bad memories of the Keisler TKO problems. Seemed like everyone had different degrees of success and failure. Also different measurements. Exactly I think what is needed is the angle of the tailshaft at the end to get a more accurate assessment ?

I have to try to find a smaller angle finder, mine won't fit. Not sure where to take a measurement on the tail shaft from since the top and bottom both have different angles
