Rear Swaybars?

I am building a 1967 Holden (australian) with a 480hp sbc in it. The car should weigh in around the 3000lb mark at a guess. The rear end is still leaf spring with the addition of a watts linkage an some caltrac bars. The front end is also reasonable stock except for strengthened lower swing arms, lowered coils, power steering rack & pinion, alloy hubs and a 7/8" sway bar. I have got a 5/8" sway bar for the back but am not sure whether or not it needs it. Will it help handling or just make the rear end want to let go more often? The rear tyres are 285/35/18s if that makes any difference.

Adding the rear anti-roll bar will increase traction in a straight line and reduce rear traction in corners. Most cars however understeer quite a bit so putting it in should just make it more neutral.

If you add the bar and have a limited slip/posi/locker, it will want to step out(oversteer) more on the curves under power. But, you are running 285 width tires that should get a pretty good bite.
Throttle induced oversteer can be fun.

Would you please explain that a little To my thinking it would seem the opposite would be true. An anti-roll bar would hold the car flatter in the corners thus limiting the wait transfer to the outside tires. and do nothing on the straight line but possibly give you a stiffer ride in bumps.

Tires are load sensitive. That is the more load on a tire the less the increase in traction. Because of that the "axle" with a more equal load on the tires will have more traction. Stiffer springs or anti-roll bars will cause more roll stiffness which will cause cause more load transfer from the inside tire to the outside on that pair of tires.
