    With the 545rfe you'll need to cut the tunnel and fabricate a new one since the 545 is a huge trans.

    The 545RFE trans is very large. I don't think there is any way you can install one in an A body without major floorpan surgery.

    I've included some pictures of the work I did.

    Thanks for the info on the 545RFE 5 speed automatic.

    Another question: What is the Chrysler p/n for the production line 6.1 L hemi engine to use for a swap (instead of the crate engine)?
    A vendor here in Ontario, Canada is quoting $6000 CAN for a 2008 production engine (includes wiring harness and manifolds etc), but I wanted to check with my Chrysler dealer for pricing.

        Nice dyno number. That means its probably ~ 400hp at the crank.

        You and I have almost the same setup except going into a 73 Duster w/ a 70 nose & 727 trans.

        Finished my Trans mount and thought I would share. Now the beast of a trans is right where I want it.

        I've read, in this forum, 485 lbs and more recently 533 lbs., they compared it to the weight of an all iron sbc. 485 lbs without accessories ? Thanks, ateam.8-[

        No, it absolutely is too big. Just installed a 545RFE tranny from PATC, in a '69 Dart, and I cut the entire floor out. It looks like I will be able to reuse the cut-out, by raising it up and adding patch pieces in to raise its height. The tranny is very fat in the middle, completely opposite of the 727 trans, which must be the 4 clutch pack and overdrive. This fatness in the middle take out the main cross member under you legs, so I will have to rebuild the geometry of hump in the cross member. I will send pics as I fab it in. I have almost 300 pics, but I need to shrink their file sizes to send to you guys.

        I went with the square look like in my Challenger. I see what it will look like in my head with the center console anyway.

        This way i have plenty of leg room still and the seats still move nicely.

        No, it absolutely does not fit without a lot of floor modifications. See FABO Forum on 3rd Gen Hemi Swaps. I just posted a lengthy expalnation of what I am going thru to weld up the floor. We have a 6.1 Hemi, 545RFE going into a 69 Dart.

        My plan currently is to buy the TCI 6X. I'm sure the floor/tunnel will have to come out.
