Its not making any sence to me how a bigger cam with 3 different seperation angle is going to make that much of a difference.

Yes i will need to add more fuel which a 350 chip will give easy but it will run and sound better thin befor.
Here is an article on understanding Lobe Separation Angle maybe it will give you more understanding of changing lsa. Also adding a larger duration cam puts the basic operating range in higher rpms. This is the reason for the torque converter and rear gear change. The stock torque converter can put a lot of load on the engine and kill vac at idle. TBI is a "speed density" system, meaning no mass air flow sensor, and meaning programing assumptions are made about the operating conditions such that if you change any of them (like exhaust flow, engine displacement, cam duration, etc.), you need to reprogram the assumptions in the computer.
