I have a 78 360 block I am putting in my Cuda that originally had a 340 and now this brace seems to short. 67 Dart GT 340 4 speed 70 AAR Cuda 408 6 barrel 96 Indy Ram original owner 2011 Hemi Durango

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

No, OP is correct. From my experiences, 318 and 340 are the same. But when I swapped my 318 out of the Barracuda for a 360, only one brace would fit the other was about an inch short IIRC. Can't remember off hand which side is short. The 360 block had the machined boss at the same location as the 318, but the boss was not drilled for a bolt at the 318/340 location. Don't know if this is true with all 360's or not (Mine is a '74 casting). Scott B. "I'm a self-made man...

On modern engines (take a look at a 5.7l hemi) the structure is incorporated into the dust cover.

Nobody will notice when painted. I would use them. The new 5.7s trans are bolted to the oil pan which will be a pita with an aftermarket pan.

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.
