This is the bracket.

Our 69 factory 383 Dart GTS has a 400 block based 451 in it using the factory 383 mount bracket set up.

Before the current 451 I has put a 440 in it using the factory K-Frame.

I'm not sure if this an original 440 mount bracket or a modified 383 bracket.
I traded a spare 383 bracket of a 65 Chrysler for it from a guy that took a 440 out of his Dart GTS to put back in a 383 since it was a originally 383 4 speed Triple Black GTS.
He sold that car to another buddy, who knowing him will be flipping it soon. lol


Looks like a factory 440 mount to me! Like I said above, it is just a 383 bracket spread apart and a piece of angle iron welded on. One was for sale last year at the Mopar Nats for $800, waaaayyyy overpriced as if you make your own it will only cost a few dollars...


The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
