sorry misunderstood the remark. what does dizzy mean, im not a total gear head im just a weekender right now any guess on the timing advance

distributor

the distrib has no provision for anything other than full Mechanical advance?
springs is the only thing you can do.
Set the base and that's about all you can do.

Otherwise you can go with any vacuum advance HEI type from any 80's GM. Then you could tune the vacuum and spring (rpm based) advance curves.
Just try to fone one that has a 4 pin module, easiest to hook up, run a ignition hot to the red wire on the coil plug and your firing.
