Wheel spin issues

Hi guys,
I've got a 67 formula S fastback
It's got a mild 440, hemi 18 spline 4 speed, strange dana s60 with 4.3 gears, 28 10.5 r15 tyres on rear (bf Goodrich), I have the front raised up just short of the droop stops.
I'm just getting ready to set this thing up and wanted to hear from guys that are either racing or have raced with similar setups.
I still have the original formula s torsion bars and rear leaf springs still in the car. ( it is an original 383/4 speed car)

Even with 1/4 throttle, she is spinning off the line.

I have a set of MH racemasters semi slicks on the way as I want to still be able to drive on the street.

Would SS springs, 6 cylinder torsion bars and an adjustable pinion snubber get me sorted or should I go down the ladder bar or slapper bar route?

I don't want to be doing massive wheel stands. I just want out of the hole nice and flat and quick so I can destroy some rice burners. :)

Cal-tracs would be my vote and the ft. end is as or MORE important than the rear.......
