Is the engine to transmission brace that goes from the bellhousing to the drivers side of the engine different for 340 engines and 360 engines? I have a 78 360 block I am putting in my Cuda that originally had a 340 and now this brace seems to short.

In the late model trucks, magnum V8s have a brace on each side from the motor mount boss to the bell, but only on automatics. Manuals did not have them.
Must not be THAT critical?

Personally wouldn't worry about it. Seen many put together with out and no evil effects. I personally have left them off many times on engines that have no way to put them on past headers etc and not had any problems. IMO they are overkill
Evidently they were put there for a reason,doubt they (Chrysler) would have went to the expense otherwise .

The unsupported portion of the SB bellhousing extends further below the block than the BB does, that's why the braces are there...to support the lower part of the bellhousing.

they moved the bolt hole sometime in the mid 70s and I think they did it again with the magnums.

Anyone have a pic of it installed? Never seen that, is it both sides on the old cars?
Thx Still looking for a pic, wondering if I should add these. Not clear on where they attach.

If it's just barely too short what about using some grade 8 washers as spacers? I have headers on mine so it came off. Never had any issues without it

Personally wouldn't worry about it. Seen many put together with out and no evil effects.

IMO they are overkill Evidently they were put there for a reason,doubt they (Chrysler) would have went to the expense otherwise . <img src="/ubbthreads/images/graemlins/Twocents.gif" alt="" /> They are put there to raise the natural frequency of the powertrain bending mode. On modern engines (take a look at a 5.7l hemi) the structure is incorporated into the dust cover.

It's got a cop motor, a 440 cubic inch plant, it's got cop tires, cop suspensions, cop shocks. It's a model made before catalytic converters so it'll run good on regular gas.
