I have a full body cadillac, same as a nova but a little heavier.

I floated my RR last weekend.

I ran 100 rr bite, 54 left,56 rear.

I am not running a lowering block on the lr.

I am running a 2 barrel carb.

I didnt really notice any difference at all on tacky during the heat. I expected it to be too hooked up. so I adjusted for the main and am not sure I went the right way??

I took out a lot of the rr, until I scale it I wont know for sure how much. I also added 50# of lead high on the lr. I removed my lr shock entirely and put a easy up shock on the rf.

The track was very dry slick, my car was no better than when I wasnt floated. I have been reading on fastboys on 4m and am not sure I understand the rr bite deal. I thought it was to make the hook less severe etc?? I dont know if I got any wrap, I never got any hook thats for sure.

I run on used IMCA g 60 tires, max tread depth were allowed to have on our cars is 4 32nds. We cant groove them etc.

the right rear bite makes the car tighter going in (sidebite), and with it being unpinned the leaf doesnt wrap and the LR multi does all the work prompting a ton of bite in LR.
The setup is pretty much a full tilt or nothing setup you need everything working together
U may want to up ur rear percentage up to 60 percent.

Did you reposition your l-r leafs?
Take them apart and move the 2nd leaf up under the eye, turn the 3rd 180 deg. and throw the 4th away. clamp the fronts together and redrill the 2nd leaf. Make sure you have the fronts clamped good and don't clamp the rear. Put her back together and run it. Should work fine.

I moved the second forward, and redrilled it, flipping the 3rd 180 would make the front shorter, and theres no way I am going to toss out the 4th with a 3200# car and expect it to work!!!!

These are camaro leafs, fastboys,fr1 etc use chrysler leafs.

How much arch do ya have in that LR spring, and have you unclamped the rear of the LR spring?

stock arch, unclamped on back only, no lowering block..

rear percent was 57.3, and bite was almost even accross the back after the changes I made at the track.

I re scaled it to 100 lr bite and am going to race it that way next.

Then Im thinking put more arch in the lr and put a lowering block in there to give it some leverage to work the spring?

Leaf, keep me posted on that set up, and how it works out for you. I disagree about the lowering block idea, as I don't see you gaining leverage, I see you loosing it.
Personally I would try putting more arch in the rr spring and a lowering block there, because you don't promote any wrap in the spring with it being floated. In essence you are only putting a taller spring in and are able to attain ride height and bite adjustments with lowering blocks. However, I ALWAYS add one leaf to the left side to get it's rate up to gain bite. I haven't tried unclamping the rear of the spring, but you can bet I will!
Good luck! BTW-----I believe in wedge, and a lot of it! You have to drive in deeper before setting the car, but it comes out of the corner better IMHO
