72 duster /6 to sbm swap help

I have a 72 demon /6 car now that I'm working on and olan the 360mag swap myself. While not overly knowledgable yet, I've been doing this same research.

First rec: check out magnumswap.com. they give a very good broad overview of what to do.

In a nutshell, you'll need to upgrade your torsion bars and radiator. You'll need a new trannie since the /6 bellhousing isn't same as on V8.
It's highly recommended to upgrade to at least front disk brakes if got all drums since you're pushing more HP.
You prob have a 7.25 rear which is weak for a bigger V8 torque, so need to swap out for 8.25 (handle up to ~350-400horse) or an 8.75 or Dana 60 to handle way more + juice.
Might as well swap in BBP wheels if you have SBP now, more wheel choices for better performance and stickie.

New engine mount and/or kframe.

There's a lot to make it last and make it safe, but it's all really doable.

Edit: oh yeah, new throttle linkage like a lokar kit. Lots of little things.
Since you have donor car, most will have to xfer over or be modified for an A body
