Need a measurement - bellhousing plane to firewall plane

How far forward of the vertical plane of the firewall is the mating face of the bell housing, measured at the 12 o'clock position? My motor mounts are goofy and I think I'm 5/8" too far forward.  This is a 5.9L Magnum (not that it matters) in a '68 Charger with a hodge podge of engine brackets.

I was under my '69 Bee today and remembered this post!

Sighting the tape end so it lined up with the flatter face of the upper firewall area, it is 2.25" to the engine/bellhousing mating plane... at least on my 383 x '69 Bee. Hopefully someone with a '68 Charger can confirm they are the same.. or different..  :shruggy:

Thank you!  ...now to go measure mine.  '69 Bee should be the same.

I might be missing something, but different engines are in different locations as I remember based on if they are /6, sb or bb.

Also, are you using the original 727, and driveshaft?

When I put my 518 tranny in, I was using a pics from a bb install and noticed his engine was closer to the firewall than mine. Now that could be because the pic was not perfectly straight on and there was no difference, but I would research this further before proceeding.

My SB seems to measure right at 2 1/4" as well.

Tranny mounts are the same between 727's for SB/BB/s6, so it stands to reason the front of the trans is in the same spot for each as well.  SB's use the same engine mounts regardless of 904/727 I believe as well, again pointing to the mate all being in the same spot.  I could be wrong.
