One additional concern should be, if the front spring eye location is changed up/down then to use angle shims at the leaf/differential to re-adjust the drive shaft / pinion angle.
Good point! What pinion angle would you dial in on a roadracing HEMI car ?
We used -4° in drag racing, but that might be a lot for the road circuit

Docford -- I'm uncertain what to advise for the pinion angle for the car you describe. I believe the Mopar Performance Chassis book, etc, advise how to do this.... you'll probably need an angle gage. (I had a racer-pro (Jim McKamey) do mine as I was also having the entire suspension balanced... back in the mid-80s.)

What were the final specs on the TBs and leafs? This is for a hemi-Cuda? Which body.. E or A? Which gen-Hemi?

On my T/A, I run the 1.24 TBs and 225 pound/inch with 5" free arch rear leafs (fiberglass mono-leafs from FlexaForm)... compressed to about 1.5" remaining arch,... and have 1.25" solid fron sway bar, 1.0" solid rear sway bar, Red re-valved Konis front/rear... car handles great, very neutral; weight is ~3150 w/o driver and with ~1/8 tank of gas (52% front, 48% rear)... this data is when the car is setup for national SCCA E/SP competition. even on the hi-speed road courses it handles great.. still relatively neutral.
I think the weight% with the 426 Hemi up front is going to be greater than what is indicated...??? I'd use a 1.0" rear sway bar to help offset the front weight.

Best bet would be removing weight from the car.. that 426 hemi is very heavy. It'd be interesting to see the actual weigh scale results, each respective corner.

Very nice!
It begs the question of what time could it turn on a dry track with more cooperative traffic?

I've really been kicking around the splined front swaybar idea. Basing it from my existing Hotchkis mounts, it really would'nt be to much of a stretch.

I assume what I am asking about is just a video or mounting visual distortion artifact, but does it look like the trans tunnel area/rear TB mounting crossmember flops around a lot based on bumps and/or cornering? Nothing else inside the car seems to move much, relative to camera, but this area. If so wow, if not nevermind.

That car is awesome! Man you got big balls running hard in the rain! Nice save too! Last time I was in the wet my car spun and had a fender bender.
Your car moves pretty good despite the weight. The leafs and t-bars must be heavy but really make a difference!
Thanks yes , the Cuda now is really fun to drive and one could even let his mom cruise it on the street
