What are the various possibilities to check and in what order?
as Mark said..check the air pressure simple things 1st...also sounds like your chassis is definatley not loaded at that point...example my nova will move around on you without Nitrous than with Nitrous..its the way we have the 4 link set up....this is totally different set up then you have but same weight transfer/chassis loading principle.
Your next step is to get the chassis loaded...I have a stock 69' camaro leaf spring car with slapper bars,weld in sub frame connectors( all the sub connectors do is resisit the car from twisting)...has a run a 5.84 @130 mph and very stable.
to make it work we placed a lot of pinion angle in the car and placed some moroso trick springs on the car..so the front end has a lot of travel ( soft )..so it tranfers weight real quick off the line and stays transferred to back tires as long as you have it under a full throttle..
