392 swap vs 340/416 build
@Tjfly4pay makes a crossmember for the T56 that’s strong enough to allow you to run torsion bars, he has a thread here or you can PM him. It works great, and takes all the guesswork out of the fabrication. You just need to do the tunnel around the new crossmember. Then you just need engine mounts for the stock K and can knock a few grand off your total that you’d spend for the tubular K and coilovers. There are headers that fit with the torsion bars.
The hardest fabrication work is for the transmission, and the crossmember takes care of most of that. I love the T56 in my car. I have the T56 install in my build thread My "new" '74 Duster- or why I need a project like a hole in the head
I really enjoy the 340 as well, but I’m considering fuel injection going forward. And if I added up my costs between building my 340 and doing everything necessary for the fuel injection I wouldn’t be far off going to a Gen III Hemi. I spent over $6k building my 340, and have more money in it since then. It runs great and puts out a little over 400 hp, but for a daily driver it’s a little high strung. And gets 13mpg around town even with the 6 speed. Adding the cost of fuel injection to that and I know I could be under that total cost with a Gen III, especially if you leave the transmission out (like you would if you’re going T56 either way).
I like the simplicity of just having a 750 double pumper on the car, but, for a daily fuel injection will be so much nicer for drive-ability. And with FI you need a computer, so, if you’re already doing that the Gen III isn’t that much more computer junk.
