We went through this with our 2.3-16 when we increased the front end weight with a supercharger/water/air intercooler system. There were other factors involved but the ultimate solution was heavier front & rear ARB's that brought the car back into balance.
Here is a link to a write-up we did on the effects of ARB changes on the car as it went through various iterations leading to the final blown configuration. It may give you some ideas.

The weight difference between the M120 with 722.6 transmission over the M117 with 722.3 trans is about 200 LB. I was able to bring the ride height back to stock using heavier springs up front for an iron block 450SLC. The car drove real nice threw the twist and turns of Deals Gap "Tail of the Dragon". Its the high speed straight line stability that seams amiss.
