I meant where the header bolts to tailpipe.  The BB mounts move the motor over AND forward, what happens to the rest of the exhaust system?  Mine seems to be in quite a bind when bolting everything back up.  I know the motor didn't move much but a little bit makes a real difference.

I kinda jumped into your project a little late, but I am doing basically the same thing you were, mine is happening because I put in power steering and I realised there was no way the steering box would fit with the BB sitting on Sb mounts.  My question is.....  did your exhaust come close to bolting back up?

Wow, that pretty much clears that up.  I do have a driveline vibration and I hope this is the source of the problem. Thanks

Does anyone know why the mounting holes are offset in a big block crossmember?  I am changing from 6 cyl to big block, and I can't see any reason to swap out crossmember.

Well............. the bad news is pretty much what I expected.  My driveline is at least 50 9/16 c-c, longer than any driveline in any first gen.  I downloaded a measurment chart from Denny's drivelines website and I'm going to get back under the car.  At least I have something I can compare to now, factory specs, my driveline, and my car.
I have also seen a lot of talk on the correct offset yoke.  Chances are good this is wrong too, can I tell if I've got the right one?

I did not know there was a unique transmission crossmember, I cannot see it making a mechanical difference, knowing a small block can bolt in the same place as the big block, however incorrect it may be.  I do have the correct front towers and my flywheel and balancer are externally balanced.  I don't have a real problem with having a custom driveline made up, I was just hoping someone would know what GM did on the 396 cars and took out some of the chance for error on my end, and give me some kind of spec to compare to the driveline I have in the car now.

Mild Modifications / 4 speed driveline length

I have a 69 with 454 and muncie 4 (m20).  The car started life as a 6cyl 3 speed. The car has a pretty good driveline vibration, and the driveline seems to be custom done at a shop.  Does anyone know what the factory length was for this application?
