OT: An A-body t-bar is shorter than an B/E body t-bar. Both length and diameter factor into the spring rate. A b-body bar of the same diameter will have a bit lower spring rate.
On topic: I don't know why you all are insistant this gentleman will be unhappy with his tbar upgrade considering his base and objectives. Take a look at the tires, rear springs and the types of use he has in his objectives. The tbars and swaybar selected will both noticibley reduce the roll he is experiencing. Could it be even higher roll resistance? Sure. But for his combination there are other places to make changes that ought to go with higher roll rate. Plus if some drag strip launches are part of the plan, which it seems to be, then staying on the soft side with the t-bars can be used to advantage.
For a good launch, 90/10 on the front shocks would a useful function. Not many companies offer that with an option to go back to near 50/50 for the street, so that will limit the options. On the drag race forum you may find some people who know off the top of their head. On the rear, it would pay to measure the shock length at reat and at compression and extended as it may not fall in stock parameters any more.
Finally, an alignment that is more favorable to the handling characteristics will make a difference too. Especially if you are going to modern radial tyres that tend to prefer a bit more negative camber than bias and cross-plies. This is true even for general use street tires like the BFG Radial T/A. Set the ride hieghts, a bit negative with the camber, and 2-3 degrees positive caster if you can, and then a very little toe in (static). The higher rear may make it harder to get even 2 degrees caster, but each car is a little different, just do the best you can.
FWIW I have found that the largest factory big block cop TBars (.96 or .98 I can't remember) work wonderfully on the smallblock version of the same car, and still play nicely with the largest stock swaybars and over the counter shocks. that spells convenience and doesn't break the bank
Yeah, it'll be a bit softer with a big block, but still will be fine to drive. I had the same thoughts about weight transfer. The last thing you want with big horsepower and tires is a car whose front-end won't move. In fact, from a drag race perspective, .96s are thick. it's all about striking a balance, and your personal expectations.
yes, you certainly will be able to feel and see the difference with .96s. No, you won't be winning any corner carving contests. and you may not care about that. I'd definitely try that 1.25" hollow swaybar from FirmFeel, that's on my own list of things to get. This is like "pick my camshaft" - thousand people w/ thousand answers

The amount or size of torsion bar required is directly related to how much stiffening has been done to the car including a welded up/reinforced K frame. Project black n blue has a welded reinforced k frame and lots of welding underneath with hemi leaf springs, torsion bars with FF sway bars and qa1 shocks. It is lowered to the minimum ride height with no compromises and only uses a 26 inch tall 10 inch wide tire...and some how it eats SRT8 Challengers on the road course with ease... Who is ahead of whom in the picture?????.... And btw both drivers are very good...
