Well, THAT didn't go as planned....

-
Measure the circumference of each slick,
If the slicks are close
it may need preload removed from the pass bar/added to the drivers bar..
 
Thx to all for your replies/ideas. Keep'em coming!

Has the front end been rebuilt my old race car would do the same as what you are describing when ball joints went bad .... Nice car seat time is your friend
I totally rebuilt the front suspension last summer including all new ball joints.

from what I gather, it needs more bite to push that side forward more, more preload on that side !.
I took apart the CalTracs last night. This and the axle are the ONLY things I haven't gone through or redone since I bought the car as a roller. First, I measured the space between each bar for preload. Neither side had any preload. Lh was like 0.050" and Rh was like 0.090"clearance. So next I started disassembly and found the Lh side was essentially frozen up and the Rh side was barely able to move. That doesn't seem right so it's all coming off. A few bolts gave me a workout but I got them out. I'll clean it all and grease it up and make sure it's all free and able to move. Then I'll start with a tad of preload on the Lh side for the next time I take it out. The rods ends on the transfer bars are also pretty frozen so those will get addressed as well. So more work under the car for the next few evenings. Then get the shift light in so we can see if ole dummy here can learn to shift on command instead of just randomly!
These old cars do give us fits...and fun!!

Those preload numbers are backwards and the driver side being locked explains why it went left.

I'd set them up per cal tracs suggestion. Driver bar a small gap, pass bar touching spring, IIRC. There is a Cal tracs tuning thread in here somewhere with the baseline. The pass bar generally will always have more preload in it.

Yup, its it stickied to the top of the race forum here:

Caltrac Tuning Info LOOK HERE
 
Got the CalTrac system all removed, disassembled, cleaned up, freed up, greased up...and reassembled last night. It all moves freely now so I believe I now have a shot at getting them to work as intended. Maybe not the first try but they should now at least be able to be tuned for this car. I intend to use that CalTrac tuning sheet - actually had it in my file some time back as it makes it pretty straightforward to tune.
Shift light due today - try to get it installed tonight assuming it arrives. Then await next outing for the car.
4.10 axle ratio swap will hopefully come a few weeks from now. I want to get this sorted out first to see what I have. Easy to limit RPM with your right foot!!
 

Update from 5/30/21...
Took the car back to try it with the freshened up CalTracs and the new programmable shiftlight. Made some test runs with varying amount if preload on the LH bar. Car was VASTLY different in how it felt today! Still had a couple issues but some were driver error-induced again. Overall a good outing testing the car. Set it's new best and learned a few things along the way.
1) It seemed to like about 3 flats of preload on the LH CalTrac bar.
2) Best 60' of 1.510
3) Best 1/8 mile of 7.118 / 94.7 mph
4) Best quarter mile of 11.317 / 115.3 mph
5) Torque conv is flashing a bit higher than I'd like at the line. Looks like right about 5000 rpm.
6) Gotta get this 4.56 axle gear swapped to a 4.10. The 11.31 run pushed the engine to 6700+ rpm out the back door. Just spinning it for no reason as it clearly doesn't make power up there - not enough cyl head for that!! It would be just about perfect to take about 600 rpm off that peak rpm.
Here's a pic from today:

And the first run off the trailer at 11.43/114.4 mph.


So in my world, it was a good day. Home safely and improved the ET from last week by 0.49 secs. Even had a .0108 and a .0048 light. Need to save those!! More work to do....
 
What diameter rear tire?
I’ll guess 28x10.5 looking at the pict.... (prob lose a dollar on this wager).
You guys know your stuff too well! These are MT ET Drag 28/10.5-15W's. Wheel wells front-to-rear can handle maybe 1 more inch in diameter. Springs are inboard and could maybe handle more width but at this power level, shouldn't really need it.
Somebody wins a dollar!!
 
Looks like the converter is slipping about 350-400rpm........so it’s working pretty well.

Converter is an 8" ATI Treemaster. This is my first experience with one if these. So far, from what I can tell, it seems to be doing as advertised. The only thing was I had asked for about 4800 flash stall and it's getting right at 5000. I doubt you can guess them much closer than that when you're welding the thing together. You could obviously tighten it up from here but before I did that, I think a 4.10 axle might drop it a tad anyway. And if not, ok too as I need less axle for dropping rpm out the back door. But THAT hinges on whether we're going to run 1/8 mile or quarter mile. Don't need it for 1/8 mile. Decisions, decisions, decisions....

After watching the video, I think u should jack the engine up more /stalling it --------------I`d try as hi as it would go w/o moving the car , once at least --
