Too much cam?

Cam timing changes the power band of the cam retarted moves up higher in the rpm's advanced moves it lower.If it hesitates and then snaps to life I would be look at the excelerator pump cams and shooters,the car lost it's hesitation with 25 degrees of timing and gave you a traction problem, sounds like to me that it needs a faster timing curve and that the cam is advanced witch picks up low end torque and this is good in a street car. If it was me I would try a quicker advance curve in the distributor and then play with the cam and shooter on the carb.
