Yup. I am kinda the ginnie pig for these and will be running the LCA cantilevered off the stock K frame, but reinforced on the front side where the stock pivot wallers out the K frame hole. This is kinda a departure from how he has them designed, as he has a brace for the pivot shaft on the end of the LCA. I ain't gonna use it.

Intuitively 9" springs make my inner happy more, well happy cause of less movement internally to the metal. Spring rate with the 440-1 Mega motor may be a tad stiffer than the KB alum short deck on the real motor. But I really don't know.

This gonna be some nice stuff, I think. The Mazzolini proparts headers didn't fit worth a damn and I had to smash some tubes on the pass side to clear the frame and TBs, so the 540 motor won't breathe now with them. Probably gonna have to get a set made custom for that motor in the car. Losing the torsion bars will help a lot IMO.
