Plymouth Duster Suspension/Tubbing Question - Drag Racing
That's the correct Caltrac setup. I failed to mention I do have the 3/4" offset spring hangers, but those don't require nearly as much fab work as mini-tubs or the 3" spring relocation kit. The only fab required is moving the spring perch on the axle housing. This is not required, but it helps getting a little bit more tire under the car instead of closer to the wheel opening.
The mopar SS springs do work, and they are affordable. I don't like buying things if I just plan to upgrade later, that's why I recommend the Caltracs.
See pic below. This is a 8" wheel with a 28x10.5 ET Street, IIRC. It didn't measure those exact measurements. Full steel car, bench seat, through mufflers, 10:50s all day all motor. As mentioned above, a full weight car capable of 10s N/A isn't going to be very mild mannered on the street. You will need a relatively loose converter and 4.56-4.88 gears and a pretty large camshaft and perhaps high compression. Ask me how I know....
Also, if you plan to run 10s, you will need the safety equipment to do so, unless you just want to make one pass.
I had the most fun when my car ran 11:50-11:75. It was super streetable, it had a solid flat tappet cam instead of a big nasty solid roller, and pump gas. Not to mention, it's pretty easy to put a 450HP engine together these days with all the aluminum head options out there.
